Hi,
I got myself a new computer and have found a little problem with my current installation. I hope someone here can help me.
System:
========================
Processor: AMD Athlon 64 X2 4200 EE
RAM: 2 x 1024 Corsair TwinX
Mainboard: ASUS M2N4-SLI with nforce4-Chipset
SATA-Harddisk: Samsung HD252KJ (250GB, 16MB Cache)
OS: Slackware 12.0 (Kernel 2.6.21.5-smp)
Problem:
========================
I want the SATA drive to hold my OS and a big data partition. Many partitions on that drive are encrypted (LUKS). When I copy anything over, say, a few MB onto such a partition, the disk stays active for a moment, then the system freezes and reboots. This is true for copies from another disk as well as for copies within the same HDD.
I'm currently running the same OS from my old IDE harddisk, installed in the same computer. Copy operations to any IDE or USB drive, encrypted or not, work flawlessly.
This is some relevant stuff from dmesg:

I've checked non-encrypted partitions on the same drive. They seem to work fine.
And there's another weird thing: Just to check things I booted a Live CD (Knoppix 5.2 c't DVD with 2.6.19.5). All copy operations work absolutely fine there, to encrypted as well as unencrypted partitions. I wasn't able to get a /var/log/messages output, since Knoppix doesn't seem to have that, but here are some dmesg lines:

Apart from the difference in sata_nv versions (3.3 for Slack, 2.0 for Knoppix), I can't spot anything fishy there.
I tried recompiling device-mapper and cryptsetup, to no avail. Next I compiled a new kernel (2.6.22.5) to check if maybe dm_mod/dm_crypt of Slack 12 were the culprits. No good, the same behaviour persists.
So now I'm fresh out of ideas, and I'm starting to grow a little sick of crashing/rebooting/fs-checking my system over and over. If anyone here has ANY idea of how to trace this, please let me know. If you need more information, just tell me what to get.
Thanks in advance!
