[Xen-users] xen kernel problem

I just noticed a problem with the -xen kernel i compiled after taking
Ian''s
advise. Using the xen kernel X has stopped working and gives errors.

Here is the /var/log/messages

Jan 25 21:23:26 xen kernel:  <7>evbug.c: Event. Dev:
isa0060/serio0/input0,
Type: 4, Code: 4, Value: 59

The last line of the log file is continously displayed on the screen and no
matter what i do, it just keeps on repeating with every new keypress.

The only solution is to reboot the system in runlevel 3.

The kernel was compiled with default config options, apart from X rest
everything seems working normal.

Any help would be appreciated.

[Xen-users] Re: xen kernel problem

Going back to the kernel shipped with the xen rpms doesn''t give any
kernel
errors / X errors

xen-kernel-2.6.12-xen3_7.1_rhel4.1.i686.rpm

Any help would be appreciated.

[Xen-users] Re: xen kernel problem

Found the solution though its slightly surprising.

I thought i will share it with the list.

When i compiled the xen kernel i compiled it for the Athlon CPU since thats
what i have on my test machine. I today compiled the kernel again with the
default Pentium optimised and X worked.

Looks like i spoke too soon. The new kernel wasn''t loaded when i tested
X.
The new kernel is rebooting continously.

Trying a noreboot on the kernel command line...

it still reboots, it happens very fast to can''t read it...

will do more tests later and post results.
