+ *      Vendor Support: 911
+ *      Board: Some Intel ICHx based motherboards
+ *      iTCO chipset: ICH7+
+ *
+ *      Some Intel motherboards have a broken BIOS implementation: i.e.
+ *      the SMI handler clear's the TIMEOUT bit in the TC01_STS register
+ *      and does not reload the time. Thus the TCO watchdog does not reboot
+ *      the system.
+ *
+ *      These are the conclusions of Andriy Gapon <avg@icyb.net.ua> after
+ *      debugging: the SMI handler is quite simple - it tests value in
+ *      TCO1_CNT against 0x800, i.e. checks TCO_TMR_HLT. If the bit is set
+ *      the handler goes into an infinite loop, apparently to allow the
+ *      second timeout and reboot. Otherwise it simply clears TIMEOUT bit
+ *      in TCO1_STS and that's it.
+ *      So the logic seems to be reversed, because it is hard to see how
+ *      TIMEOUT can get set to 1 and SMI generated when TCO_TMR_HLT is set
+ *      (other than a transitional effect).
+ *
+ *      The only fix found to get the motherboard(s) to reboot is to put
+ *      the glb_smi_en bit to 0. This is a dirty hack that bypasses the
+ *      broken code by disabling Global SMI.
+ *
+ *      WARNING: globally disabling SMI could possibly lead to dramatic
+ *      problems, especially on laptops! I.e. various ACPI things where
+ *      SMI is used for communication between OS and firmware.
