reiserfs - problems mounting after power outage

From: Jeff McWilliams (

I'm having difficulty mounting a reiserfs partition after a power outage.

This is 2.4.0-test9 compiled with reiserfs as a module, and
the ide.2.4.0-t9-6.task.0923.path IDE patch - mostly to get updated support for
the 3WARE IDE RAID controller.

/dev/sda is the 3ware escalade raid mirror - two Maxtor 20 gig drives.

reiserfs is compiled as a module, the distribution is Debian Linux

uname -a shows:
Linux ns2 2.4.0-test9 #1 Wed Dec 6 16:28:45 EST 2000 i586 unknown

/etc/fstab shows:

# /etc/fstab: static file system information.
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/sda1 / ext2 defaults,errors=remount-ro 0 1
/dev/sda5 none swap sw 0 0
proc /proc proc defaults 0 0
/dev/sda6 /var/www reiserfs defaults 0 0
/dev/sda7 /home reiserfs defaults,noauto 0 0
/dev/fd0 /floppy auto defaults,user,noauto 0 0
/dev/cdrom /cdrom iso9660 defaults,ro,user,noauto 0 0

The partition I'm having trouble with is /dev/sda7. /dev/sda6 recovered okay.
/dev/sda7 doesn't have a lot of data on it, and I CAN deal with the lost data,
but it doesn't leave me with a very good feeling of confidence in reiserfs
if I can't successfully recover from a power failure.

What happens when I type mount /dev/sda7 is this:

reiserfs: using 3.5.x disk format
reiserfs: checking transaction log (device 08:07) ...

and then it hangs. I then have to hit the reset button to reboot.

I've tried running reiserfsck with --check, --correct-bitmap,
--rebuild-sb, and --rebuild-tree. NO luck there.

debugreiserfs /dev/sda7 shows:
