Bug 144756

I am transferring a large amount of media files to my RAIDZ of 3x2TB disks through Samba. After about 10-15 minutes I get this error 

msk0 watchdog timeout



Another time I got this error while using grep on the machine

Another time I got this error when I wasn't typing on my server.

Fix: 

No idea.
How-To-Repeat: My hardware is Asus P5Q-E, 2x2GB PC800, Geforce 8800 GTS 640MB, 2x250 GB in RAID 1 ZFS, 3x2TB in RAIDZ. Transfer a large amount of files (approx 50 MB/s) in Samba to the RAIDZ. I've tried both LAN ports on my motherboard, and they give this error.
