Is this issue also present in kernel 2.6.19?

Comment 5 sebastienBRICE 2007-02-24 07:11:30 UTC
can perhaps help any body
Comment 6 Dmitry Torokhov 2007-02-24 10:51:43 UTC
Unfortunately the dmesg seems to be truncated. Please try booting with 
log_buf_len=131072 to allocate bigger buffer. Thanks!

Comment 8 Dmitry Torokhov 2007-02-24 19:35:54 UTC
That was a complete dmesg, unfortunately it did not have any debug 
information ;) Could you please try generating it once more, this time using 
both log_buf_len and i8042.debug options? Thanks!

Does it help if you boot with i8042.nomux?
Comment 11 Thomas Riedel 2007-05-15 01:06:43 UTC
I have this problem too with 2.6.19-gentoo-rx, 2.6.20-gentoo-rx and
Last working version is 2.6.18-gentoo-r7 (based on
Distribution is Gentoo.
Hardware is an Amilo A 7600 with an PS2-keyboard connected.
The problem does not occur on every boot, only sometimes.
Both keyboards do not work when it happens (not the internal one from the laptop
and not the external PS2).
Tried all options with i8042 including i8042.nomux but it does not help.
Comment 12 Natalie Protasevich 2007-06-23 01:45:22 UTC
Any update on the problem?
Comment 13 Philippe Coval 2007-07-01 17:50:59 UTC

Debian is running on my amiloa cy26 and have no such issue.

I use 2.6.20 patched kernel ( rt and dsdt )

$ uname -a
Linux nrv 2.6.20-k7-amiloa-rt #1 PREEMPT Sat Mar 10 13:02:49 CET 2007 i686 GNU/Linux

$ cat /proc/cmdline
root=/dev/hda6 ro  lapic

Have you patched the DSDT ? , which version of BIOS ? tell us more please

Else, fell free to use my debian kernel package and/or .config soon at
