-current freezes

Hi everyone,
I've been making lots of test to trace why my -current box was freezing. Cuz
it was, it really froze, I mean the Siberia kinda freeze, no error msg, no
droping in debugger, nothing.
At the beginning it seemed random so I started to undo the last changes I made.
So I made a plentyfull bunch of kernels, taking out one line at a time and
deinstalled a few 3rd party ports. And finally, I found out that it didn't
help. Bugger. The last change I didn't undo was the cvsupdate. So I deleted
all of my src and obj and cvsup tag=RELENG_5_2. And sure as getting out of
Siberia to move in Chernobyl, things went back to normal (execpt for sound,
which I lost, and some other details that makes downgrading so much fun).
I think I can pinpoint 2 problems. One is between atapicd and my DVD-RW, which
is being discussed in another email by someone else in this list. The other is
GEOM. First, there were no more "GEOM: create disk ad0 dp=..." at boot time.
Then, at shutdown, the syncer was taking much more time and tries then it
usually takes. Also, especially for my GBDE partition, whenever the "writing
to disks" buffers were being very used, ice cube it went and much
inconsistencies were detected at boot, even failing to background the fsck.
I don't have much more details then that as it wouldn't core dump, nor go in
debugging or anything. But I'll try to give as much details needed if asked
so. Here is the usual:
