kernel 2.6.15-pa1 and 2.6.15.1-pa4 fault on HIL keyboard event

Hello,

when I touch any key of my HIL keyboard, the kernels mentioned above fail immediately.

The machine in question is a HP9000 735/125 running Gentoo Linux, using gcc-3.3.6, binutils-2.16.1 and glibc-2.3.4.20040808-r1.

If dmesg -n 7 was issued (obviously by an ssh session) or I press a key before the rc scripts run, then I get an output like
http://www.richardwalter.de/Backtrace%202.6.15_p1%20on%20keyboard%20event%20second%20try
and the machine does not move any further.

The kernel sources are hppa-sources-2.6.15_p1 from portage, the .config file is
http://www.richardwalter.de/.config
the System.map is
http://www.richardwalter.de/System.map.bz2
and the resulting vmlinux looks like this one
http://www.richardwalter.de/vmlinux.bz2
(I compressed the latter two for bandwith-limited people)

I have been able to locate the crash to the file sftp://[email protected]/usr/src/linux/drivers/input/input.c
in the function
void input_event(struct input_dev *dev, unsigned int type, unsigned int code, int value)
to the line 182 which says

			if (handle->open)

Unfortunately I have not been able to locate the source of this error.

If it is of help, I also inspected the CPU instruction on adress 0c681093, according to gdb it says
ldw -c(r3),r19

I have experienced the similar problem on 2.6.15.1-pa4, but did not intercept it to the same depth. Up to now, I could not test any post-2.6.15.x-kernels, and the pre-2.6.15-kernels in portage did not have that problem.

Thanks for help
