Filesystems Raid, ReiserFS and hours of fun

I am using a (ADAPTEC CHIPSET)Serial ATA, CERC-SATA-6CH Controller
I am also using SUSE 9.1 Pro (2.6.4-52-smp)
I highly doubt I am using IDE-TCQ unless it's enabled by default.
Hope this helps narrow it down.

Well, from what you described, as long as you did a clean shutdown, I
think it to have been part of the problem this time. However, with reiserfs
(and probably other journalled filesystems) it is extremely dangerous, since
proper operation of the journal depends on known, physical commit states
when the drive acks a write, the fs expects it to be physically written).
W/write caching, it is possible for a hardware or even a software failure to
lose the cached data before it has been committed to the platter. So, I
would recommend disabling it. This doesn't help your current problem--I've
What kernel are you running? The only threads I've seen recently are
a) some reports of reiserfs corruption with 2.6.8.? kernel
b) some reports of reiserfsck corruption with IDE-TCQ enabled in 2.6
