PROBLEM: 2.6.9-rc3, i8042.c: Can't read CTR while initializing i8042

[Ronald Moesbergen]

Hi,

Since 2.6.9-rc3 (I tested rc3-bk3 also) on 3 out of 10 boots my PS/2 
keyboard is dead and 'i8042.c: Can't read CTR while initializing i8042' 
shows up in my logfile. Google found this:

http://marc.theaimsgroup.com/?l=linux-kernel&m=109463125415432&w=2

which suggests to add i8042.noacpi=1 to my boot parameters, but 
unfortunately that doesn't help, the kernel doesn't even recognize this 
option. Reverting back to 2.6.9-rc2 fixes it. The machine is a P4 3Ghz 
HT, E7205 chipset, ASUS P4P8X board.

For E7xxx systems you need to disable USB legacy support in the BIOS
because SMM only works on the boot processor. There is a patch to
automate it in 2.6.8.1-ac you can also borrow

For the record, having to disable USB legacy for i8042 initialization to
work reliably also seems to apply to my i850 based motherboard (Asus
P4T533-C).

(About four out of five boots the i8042 initialization fails with
vanilla 2.6.9-rc3 when USB legacy is enabled.)


Thanks,
Håkan

Same problem on a Dell Dimension 8250. However I couldn't find an option
on the BIOS to disable usb legacy support. 

The only thing that worked was booting with 'acpi=off'.
