Keyboard problem
Hello,
we currently have the following problem...
Background:
Evaluating linux kernels for a series of machines with 16,32 and 128Mb.
On all machines with have tested a linux kernel 2.4.26 (Damm Small Linux
3.1) successfully (including X) with minor problems.
Switching to linux kernel 2.6.18 (Debian stable Etch) shows the same
positive result with the exception described below:
The problem:
Booting a kernel 2.6.18 (actually Debian etch) on the 16Mb machines results
in a not functional keyboard. The following excerpt from the dmesg log shows
that a keyboard is found.
...
[ 4.577000] serio: i8042 AUX port at 0x60,0x64 irq 12
[ 4.580000] serio: i8042 KBD port at 0x60,0x64 irq 1
[ 5.172000] input: AT Translated Set 2 keyboard as
/class/input/input0
[ 5.173000] evbug.c: Connected device: "AT Translated Set 2
keyboard",isa0060/serio0/input0
...
The keyboard is fully functional upon entering the GRUB boot loader menu.
At the login prompt the keyboard does not respond /accept any input!
The above mentioned hardware is using the super-IO chip "NSC PC87306".
Booting the kernel with the i8042.debug option shows some activity mainly
in the initialization phase of the keyboard device. Afterwards no actitity
from the debug output is observed.
What has changed since Kernel 2.4 and Kernel 2.6 that has this impact?
If anyeone could give us an advice or hint to solve this problem, it would
helps.
Best regards
Ullrich Schicke
