[parisc-linux] evms_vgscan crash hppa kernel

[joel.soete@freebel.net]

Hi all,

I just apply evms-0.2.3 patches against hppa kernel 2.4.9-pa78.
This kernel compiles, boots and runs also fine on my b180.

But when I launch evms_vgscan the kernel crash with following message:

...
Kernel Fault: Code=15 regs=124fc6c0 (Addr=faf00918)

a "grep 1018c3 /boot/System.map"
1018c394 t evms_ioctl_cmd_get_minor

I would like to debug this by obtaining a core dump of the kernel after the 
reboot but I do not know how? (I did not find back the mail explaining how to do 
it in detail)

Thanks in advance for help,
        Joel
