Hello,
I've now managed to capture the 'panic' output of 2.4.21.
I was running 2.4.20 for quite some time on a Mandrake 9.0 base on a
Pentium IV 1.5MHz PC. When 2.4.21 came out I patched the source and
upgraded to it as I usually do for kernel upgrades.
However, mounting the CDRW makes it all go crappy and it dies. See
attached panic output.
The command was issued on the PC's own attached console, but the
output's captured on an attached serial console (command was 'mount
/mnt/cdrom2' entered in BASH without starting X, etc).
Thanks
Dave

man ksymoops
You'll have to pardon my ignorance, but I've never dealt with the murkey
depths of kernel bashing before!
I now attach a 'ksymoops' version of my 'panic' output and hopefully it
means more to you guys now.

Here's some debug output from the crash after mounting my AOpen CD-RW drive
using ide-scsi on 2.4.21 (Athlon XP 1800+ / NVidia nforce chipset).

Some more info on this (in case anybody cares). I just threw out the AOpen
drive and put in a brand new Sony DVD RW DW-U10A. The kernel strill crashes
as soon as I mount the drive. So I guess its independent of the drive used.
regards,
Ralf
