Hi, 

I've seen HEAVY file corruption on unwanted reboots (like pressing the reset 
button accidently) on reiserfs with this kernel on 3 machines now. 

The symptom is that it finds a LOT of files to unlink on journal replay, 
which I find suspicious as those machines are lightly loaded. 

I didn't follow the development too closely the last few weeks, but I 
believe that something turned worse in this respect lately. 

Note that reiserfsck doesn't find any error in the file system structure 
before and after the journal replay on reboot, 
still many files (especially those that were not touched for several hours 
before the reboot) contain complete garbage after the journal replay.

Were these files being written to near the time of the reboot?

 Hmmm, not good at all.  Are these 3 systems IDE or scsi?  Do they run
 additional patches on top of pre7?  What kernels  pre7 have you tried
 that didn't show this problem?

All IDE. The kernel that didn't show this problem was 2.4.16 (plain). No 
additional patches on 2.4.19-pre7.

 Please tell us everything about your IDE config.  Jens and I are already
 trying to track down some odd reiserfs + ide problems on 2.4.19pre7, but
 so far that was only with our barrier write patches applied.

There is not much common. two of them are VIA 686 southbridge (KT133A, 
KT333), one is something older, a Pentium chipset. 

DMA 100 and DMA 66. We all use those Maxtor 80GB EIDE disks.

Any suggestions on how I might reproduce locally?

not much. maybe try a lot of open, unlinked files when pressing reset and 
then check the md5sum's of all files..
