First I hade this two errors. I got them when I tried to acces one of my SCSI devices; 2HD + 1CD. When I got them my NT frees for about 1~3 min. and almost always only event 11 is reported about 5~15 times!!
Now I can't boot my computer with out removing the scsi connector on the 2940 UW board. Otherwize it hangs when the boot-blue screen starts.
The driver detected a controller error on \Device\ScsiPort2.
The device, \Device\ScsiPort2, did not respond within the timeout period.
