[2.4.6, reiserfs] kernel BUG at prints.c:332!

[Andreas Muck]

Hi,

I recently converted most of my filesystems from ext2 to reiserfs and
noticed regulary oopses (?) on recovered SCSI errors. I'm not sure if
it's really a kernel issue, or compiler related, but I thought I'd
report it anyway.

The kernel/compiler is: Linux version 2.4.6 (root@mantuzo) (gcc
version 2.95.4 20010703 (Debian prerelease)) #1 Thu Jul 12 13:32:47
CEST 2001

Here's the messages I get when a recovered SCSI error occurs on the
reiserfs:

SCSI disk error : host 0 channel 0 id 6 lun 0 return code = 8000002
Info fld=0xed07, Deferred sd08:31: sense key Recovered Error

The processes accessing the reiserfs (or maybe only the affected file)
will hang in IO wait forever, even SysRq-sync fails on the partition.

I haven't had any more problems since converting the disk back to
ext2.
