The core DRM vblank code is missing a check for this case however; even after IRQ disable, the vblank code will still have the vblank_enabled flag set, so unless we track the fact that they're disabled at IRQ uninstall time, when we VT switch back in we won't actually re-enable them, which means any apps waiting on vblank before the switch will hang. This patch does that and also adds a sanity check to the wait condition to look for the irq_enabled flag in general, as well as adding a wakeup to the IRQ uninstall path. Fixes fdo bug #18879 with compiz hangs at VT switch.

Note that "orinoco: Process bulk of receive interrupt in a tasklet" did not preserve locking semantics on what is now orinoco_rx.

While the MCS index reporting to mac80211 was indeed fixed by the patch, it did not take into account that the ath9k rate control algorithm was updating private tables based on this index and the index comes through the rate control API call, i.e., based on mac80211 TX status call. In addition, it looks like the "fix" to remove +1 from TX status 'count' field was not correct based on ieee80211_tx_status() implementation that counts the total of count values, but starting from -1, not 0. The TX status reporting for frames using MCS needs to be fixed somehow, but it does not look like there is any easy fix for the ath9k rate control algorithm, so the best option now seems to be to revert the change and bring it back once the rate control code is cleaned up to handle this better.

It only acts as boolean value to indicate if the frame must be encrypted or not. The way rt2x00_set_field32() worked it would grab the least signifcant bit from txdesc->cipher and use that as value. Because of that WEP 64 and TKIP worked since they had odd-numbered values, while WEP 128 and AES were even numbers and didn't work.

The commit merged TX and RX interrupt code into a single routine that schedules NAPI, but no locks were introduced. This causes irq races, so when irqs are enabled and netif_rx_schedule_prep() returns 0, nobody disable the interrupts again. This leads to interrupt storm and finally to the lockup.

As suggested, the patch now generates a random address so that the user can go on and use the hardware. In any case a message is also shown to warn on the unexpected condition. This seems to happen with newer HW implementation of the sis900 chipset, since this never came up before. Patch is against vanilla 2.6.28 (but the driver doesn't change so often, so it will probably apply to older/newer versions too). See bugzilla ID 10201 and 11649 and ignore the previous patch.

This is to be used by drivers that need to tie several hardware interfaces to a single NAPI poll scheduler due to HW limitations.

For now, we do the simple thing: log specific messages to the log and let the thinkpad-specific event pass to userspace. In the future, these events will be migrated to generic notifications and subsystems. These alarms are NOT available on all ThinkPads. E.g. the T43 only issues 0x6011 and 0x6012.

We have found that the vendor chipset identification string (provided in brackets) changes frequently and is of no use to us. The rest of the board string sometimes changes in subtle ways, e.g. whitespace or variations in capitalization. The new comparison code checks only a part of the supplied DMI board string, trimming the bracketed content, whitespace, and ignoring case as necessary. This fixes a bug where an IP35 Pro running an early BIOS would not be detected without the force=1 module parameter, and also speculatively fixes other similiar issues.

On machines with low amount of memory, all skb meet the hardware limitation, so no copy is needed. We detect this situation using a new device flag, set to one if one GFP_DMA skb was ever allocated by b44_alloc_rx_skb().

In atmel_spi_setup() there is comment that max_speed_hz == 0 means as slow as possible and divider is set to maximum value. But in atmel_spi_transfer() function is check against not zero max_speed_hz with EINVAL returned. Probably driver should setup divider for each transfer based on transfer->speed_hz value, but I think that would be not necessary overhead as all used devices have constant clock. Below patch works fine for me.

However, returning -ENODEV causes the driver layer to silently ignore the driver as it assumes the probe did not find anything and was only speculative. To make life easier to discern why a driver is not being attached, change to returning -EINVAL, which is a better description of the fact that the driver data was not valid. Also add a set of dev_dbg() statements to the error paths to provide an better explanation of the error as there may be more that one point in the driver.

This false detection will occur if the restarted XPC comes up within the five-seconds preceding one of the other XPC's heartbeat check (which occurs once every twenty seconds). The detection of no heartbeat results in the detecting XPC deactivating from the just restarted XPC.

As a result, the reported light sensors readings are much too low. Via experiments leading up to this patch, it seems only the ALV0 is reporting data, and the most useful value therein is a 10-bit big-endian value at offset 6. This suggests that a new protocol was added as a backward-compatible replacement on top of the old one. This patch makes applesmc report the improved light sensor reading for the new machines, on a scale in conformance with earlier ones.

This routine is responsible for probing the available connectors, encoders, and crtcs, looking for modes and putting together something reasonable (where reasonable is defined as "allows kernel messages to be visible on as many displays as possible"). However, the code was a bit too aggressive in setting default modes when none were found on a given connector. Even if some connectors had modes, any connectors found lacking modes would have the default 800x600 mode added to their mode list, which in some cases could cause problems later down the line. In my case, the LVDS was perfectly available, but the initial config code added 800x600 modes to both of the detected but unavailable HDMI connectors (which are on my non-existent docking station). This ended up preventing later code from setting a mode on my LVDS, which is bad. This patch fixes that behavior by making the initial config code walk through the connectors first, counting the available modes, before it decides to add any default modes to a possibly connected output. It also fixes the logic in drm_target_preferred() that was causing zeroed out modes to be set as the preferred mode for a given connector, even if no modes were available.

The reason is that the shutdown sequence puts the hardware into D3 sleep, and the commit causes us to claim that it then is in D0 (running) state just because we don't understand the PM capabilities. Which then later makes "pci_set_power_state()" not do anything, and the device never wakes up properly and just returns 0xff to everything. Reported-by: Yinghai Lu Acked-by: From: Rafael J.
