[FreeBSD] Kernel panic - winny ZFS?

Witam.

Mam problem z FreeBSD 8.2-p4 64bit (kernel GENERIC) na maszynie z
Celeronem 220 1.2GHz, 2GB RAM.

Od kiedy zacz±³em u¿ywaæ ZFS, maszyna co kilka dni siê resetuje.
Load Average w momencie resetu raczej nie przekracza 0.1

Zajêto¶æ poola: 130GB z 1TB.
"zpool status" nie pokazuje b³êdów, "zpool scrub" te¿ ostatnio zrobiony.

Nie mam fizycznego dostêpu do maszyny, a wiêc nie bardzo mogê sprawdziæ
problemy sprzêtowe. Ale zanim zacz±³em u¿ywaæ ZFS, serwer by³ przez 3
miesi±ce stabilny.

Stacktrace pokazuje podobne miejsca w kodzie (fs/zfs/arc.c) przy ka¿dym resecie:
