Re: 2.6.19-rc2 - total hang with libata, CDRW and grip

Ok, now I've got a bunch of error reports from the 120GB HD as well,
which I'm using for a staging disk with Bacula for backups.  A bunch
of data gets written and then read from the disk before being written
to tape.  I see the following errors in the logs:

This is 2.6.19-rc2, libata, regular old IDE running an HPT302 Rev 1
controller with two 12gb HDs, an 18G SCSI disk holding /, /usr, /var &
/boot, dual CPU Xeon PIII 550mhz, 768Gb RAM, Debian unstable updated
within the last two days.

The filesystem (/staging) gets remounted read-only.  Now when I run
badblocks against the drive, it just complains and complains about all
the blocks.  

If I reboot, the system comes up cleanly and I can access the drive
again.  A pass with badblocks completes, as does doing the various
pvcreate, vgcreate, lvcreate, mke2fs commands to setup the filesystem
all over again on the disk. 

It's /dev/sdc1 hold the PV, holds the VG, holds the LV, holds the
filesystem.

I can either reboot the system and get more details, or I can leave it
like it is now and try some suggestions to get the disk back online.
