Hello,

I have problem with a CERC 1.5/6ch raidcard. After some days, it's stop
responding and I can't write to my volume.

This is what I got from /var/log/messages:

tellus kernel: aac0: COMMAND 0xc719c300 TIMEOUT AFTER 29200 SECONDS
tellus kernel: aac0: WARNING! Controller is no longer running! code= 0x100

..and the only thing that can unlock the volume is a reboot.
The machine is a Dell poweredge 1800, and it runs FreeBSD 6.1.

Any ideas how to workaround this problem?

Thanks,

Viktor Holmlund
