Dear List,

When writing to a DVD RAM on my system I got >48000 lines of compliant in
my system logs (sample below) and the file was corrupt. The final error keeps
occurring and the logfile is growing at 40kb/minute which isn't good.

There is a kernel oops bug down done messages a way in the ext2 module.

After rescuing my data I tried to eject the disk (eject /media/cdrecoder) - it
removed it from the mtab but the eject never completed so the disk is currently
stuck in the driver and the system is still throwing messages.

Anyway I must go a reboot now before my logs fill up.
