My FreeNAS/FreeBSD configuration on D945GCLF2 / Atom 330 VS “panic spin lock held too long”

UPDATE 2009-09-03
Still running without any issues :)

UPDATE 2009-08-01

Re-installed FreeNAS this weekend and the problem didn’t come back!
Disabling Hyperthreading fixed it!

UPDATE 2009-07-26

Disabling Hyperthreading in the Bios seems to do the trick, I haven’t yet got the error again, I am crossing my fingers.

UPDATE 2009-07-21

Now I am trying to disable Hyperthreading to see if my problem will go away, stay tuned.

ORIGINAL POST

I had some “panic spin lock held too long” problem, my FreeNAS box was freezing without any reasons.

Here’s what I did:

1. Resetted the Bios to default settings (I had turned OFF many things before)
2. Installed using full install amd64 (I was using an embedded install before)
3. System -> Advanced -> activated Power Daemon
4. Network -> LAN -> activated Device Polling
5. Network -> LAN -> Type 1000baseTX / Full-Duplex

And since then no more “panic spin lock held too long”.

Unfortunately, the problem came back :( It seems to be related to when I leave mounted shares on my Ubuntu dektop for a long period without activity. I re-installed my NAS directly with FreeBSD/Samba and the same problem happened again.
