Kernel Bug Tracker – Bug 7818
no keyboard activity after successful boot
Last modified: 2007-11-15 13:50:44 UTC
Most recent kernel where this bug did *NOT* occur:220.127.116.11
Hardware Environment:laptop fujitsu siemens A7620
Software Environment: GNU bash, version 3.1.17(1)-release (i486-pc-linux-gnu)
Problem Description: hitting key product no effect
Steps to reproduce: compiling a release candidate 2.6.20 precursor kernel
Is this issue also present in kernel 2.6.19?
this issue is also present in 2.6.19, only 2.6.18-1 works well
Can I please get full dmesg of boot with i8042.debug=1 on the kernel command
Created attachment 10521 [details]
can perhaps help any body
Unfortunately the dmesg seems to be truncated. Please try booting with
log_buf_len=131072 to allocate bigger buffer. Thanks!

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?
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 18.104.22.168).
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.
Any update on the problem?
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
Please see this for some details: Thx.
