Bug 118434 – hppa-sources-2.6.15_p1 crash on HIL keyboard event

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Richard Walter 2006-01-09 11:18:09 UTC]

My HP9000 735/125 workstation is equipped with HIL keyboard and mouse. When the machine boots up with a kernel built from hppa-sources-2.6.15_p1, it crashes immediately when I press any key on the keyboard with the message
Kernel Panic - not syncing: Kernel fault

Further Information will be attached immediately

.config of the kernel

This is the .config file of the kernel. It's made from an older .config via make oldconfig.

dmesg of the kernel

This is the dmesg output from the kernel. It does not look much different from what I am used to see from older kernels.

more intense chrashlog

I did dmesg -n 7 via a ssh session, and then I got this output on the screen when I touch a key. This crashlog is hand-typed from the screen, so it may contain typos. If you suspect a typo of importance, I have also made screenshots with my digicam which we can use to find out such errors.

Added the URL here so I can find it back later on to work on this :)

[Comment 6 Richard Walter 2006-01-21 12:27:44 UTC]

using printk() I could locate the point of the crash to the file
drivers/input/input.c, line 182, which says
if (handle->open)
the line is in
void input_event(struct input_dev *dev, unsigned int type, unsigned int code, int value)

[Comment 7 Richard Walter 2006-04-09 07:19:01 UTC]

The problem is fixed in newer upstream versions (I tested 2.6.16-pa11 from www.parisc-linux.org).
The versions in the portage tree newer than the reported one (2.6.15-pa1) either have the same error (2.6.15-pa4) or don't build on my machine (2.6.16-pa0).

As soon as there is a working version of hppa-sources in the portage tree which does not have the bug any more and does build and run on my machine, I will close this bug on my own.

btw: 2.6.16-pa0 has the same buils error as reported by upstream here

[Comment 8 Richard Walter 2006-04-21 15:33:53 UTC]

The crash is fixed in
sys-kernel/hppa-sources-2.6.16.5_p11
keyboard works, cannot trigger a system crash by just pressing a key.
