The box has no HiSax card installed. the reason for the crash is add_timer() done on an already running timer. This happens because for some reason CARD_INIT is called twice. this patch works this problem around by using mod_timer() - this gets a booting system - but it would be nice to figure out why CARD_INIT is done twice. the ISDN config section (generated via make randconfig) is this: # # ISDN feature submodules # # CONFIG_ISDN_DRV_LOOP is not set CONFIG_ISDN_DIVERSION=y # # ISDN4Linux hardware drivers # # # Passive cards # CONFIG_ISDN_DRV_HISAX=y # # D-channel protocol features # CONFIG_HISAX_EURO=y CONFIG_DE_AOC=y # CONFIG_HISAX_NO_SENDCOMPLETE is not set # CONFIG_HISAX_NO_LLC is not set # CONFIG_HISAX_NO_KEYPAD is not set CONFIG_HISAX_1TR6=y CONFIG_HISAX_NI1=y CONFIG_HISAX_MAX_CARDS=8 # # HiSax supported cards # CONFIG_HISAX_16_0=y # CONFIG_HISAX_16_3 is not set # CONFIG_HISAX_TELESPCI is not set CONFIG_HISAX_S0BOX=y # CONFIG_HISAX_AVM_A1 is not set CONFIG_HISAX_FRITZPCI=y CONFIG_HISAX_AVM_A1_PCMCIA=y CONFIG_HISAX_ELSA=y CONFIG_HISAX_IX1MICROR2=y CONFIG_HISAX_DIEHLDIVA=y # CONFIG_HISAX_ASUSCOM is not set # CONFIG_HISAX_TELEINT is not set CONFIG_HISAX_HFCS=y # CONFIG_HISAX_SEDLBAUER is not set CONFIG_HISAX_SPORTSTER=y # CONFIG_HISAX_MIC is not set # CONFIG_HISAX_NETJET is not set # CONFIG_HISAX_NETJET_U is not set # CONFIG_HISAX_NICCY is not set # CONFIG_HISAX_ISURF is not set # CONFIG_HISAX_HSTSAPHIR is not set # CONFIG_HISAX_BKM_A4T is not set # CONFIG_HISAX_SCT_QUADRO is not set # CONFIG_HISAX_GAZEL is not set # CONFIG_HISAX_HFC_PCI is not set # CONFIG_HISAX_W6692 is not set # CONFIG_HISAX_HFC_SX is not set # CONFIG_HISAX_DEBUG is not set # # HiSax PCMCIA card service modules # # # HiSax sub driver modules # CONFIG_HISAX_ST5481=y CONFIG_HISAX_HFCUSB=y # CONFIG_HISAX_HFC4S8S is not set CONFIG_HISAX_FRITZ_PCIPNP=y CONFIG_HISAX_HDLC=y # # Active cards # CONFIG_ISDN_DRV_ICN=m CONFIG_ISDN_DRV_PCBIT=m CONFIG_ISDN_DRV_SC=y # CONFIG_ISDN_DRV_ACT2000 is not set CONFIG_HYSDN=m # CONFIG_ISDN_DRV_GIGASET is not set # CONFIG_ISDN_CAPI is not set CONFIG_PHONE=y CONFIG_PHONE_IXJ=m Signed-off-by: Ingo Molnar <mingo@elte.hu> Cc: Karsten Keil <kkeil@suse.de> Cc: Kai Germaschewski <kai@germaschewski.name> Cc: "Rafael J.

* i4l: Fix random hard freeze with AVM c4 cardKarsten Keil2007-10-18
| | | | | | | | | | | | | | | | | | | | | The patch - Includes the call to capilib_data_b3_req in the spinlock. This routine in turn calls the offending mq_enqueue routine that triggered the freeze if not locked. This should also fix other indicators of incosistent capilib_msgidqueue list, that trigger messages like: Oct 5 03:05:57 BERL0 kernel: kcapi: msgid 3019 ncci 0x30301 not on queue that we saw several times a day (usually several in a row). - Fixes all occurrences of c4_dispatch_tx to be called with active spinlock, there were some instances where no lock was active. Mostly these are in very infrequently called routines, so the additional performance penalty is minimal.

* [NET]: Make /proc/net per network namespaceEric W. Biederman2007-10-10
| | | | | | | | | | | | | | | | | | This patch makes /proc/net per network namespace. It modifies the global variables proc_net and proc_net_stat to be per network namespace. The proc_net file helpers are modified to take a network namespace argument, and all of their callers are fixed to pass &init_net for that argument. This ensures that all of the /proc/net files are only visible and usable in the initial network namespace until the code behind them has been updated to be handle multiple network namespaces. Making /proc/net per namespace is necessary as at least some files in /proc/net depend upon the set of network devices which is per network namespace, and even more files in /proc/net have contents that are relevant to a single network namespace.

* ISDN HiSax: uninitialized return in hisax_cs_setupFlorin Malita2007-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | Coverity (1792) spotted a possibly uninitialized return value in case of kmalloc() failure: 1116 static int hisax_cs_setup(int cardnr, struct IsdnCard *card, 1117 struct IsdnCardState *cs) 1119 int ret; 1120 1121 if (!(cs->rcvbuf = kmalloc(MAX_DFRAME_LEN_L1, GFP_ATOMIC))) { 1122 printk(KERN_WARNING "HiSax: No memory for isac rcvbuf\n"); 1123 ll_unload(cs); 1124 goto outf_cs; ... 1165 outf_cs: 1166 kfree(cs); 1167 card->cs = NULL; 1168 return ret; The straightforward solution would be to just add the missing initialization but hardcoding the return value in the out_cs branch (only taken on failure) seems to work just as well and it allows killing a couple of other lines too.

| | | | | | | | | | | * trim trailing whitespace * remove CONFIG_PCI ifdefs, this driver is always PCI (Kconfig enforced) * remove return statements at the tail of a function * remove indentation levels by returning an error code immediately.
