Hi !

I experienced a Oops with all versions  of the kernel newer than 2.2.x :

Here is the Oops processed by ksymoops. In this case, it was with
2.4.1-ac6.
This oops seems related to ax25 (hamradio) use. I can have access to
magic keys
(but the reboot one, but I _never_ managed to have this one to work,
maybe a
configuration problem with my French keyboard ?).
After trying a remount, I got :
SysReq : Emergency Remount R/O
Remounting device 03:02... Scheduling in interrupt
Kernel BUG at sched.c:714!
incalid operand: 0000 ... etc. etc.

ksymoops 2.3.7 on i586 2.4.1-ac6.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.1-ac6/ (default)
     -m /boot/System.map-2.4.1-ac6 (specified)

Warning (compare_maps): ksyms_base symbol
__VERSIONED_SYMBOL(shmem_file_setup) not found in System.map.  Ignoring
ksyms_base entry
