I've gotten them as far back as 2.x on one machine. > bt0: BT-948 FW Rev. 5.05R Ultra Narrow SCSI Host Adapter, SCSI ID 7, 192 CCBs Run the exact same firmware rev too. I see this on a machine running 3.4-RELEASE and previously - before the move to the current location - this machine was also running on the 2.x. The other machine with the exact same controller, same motherboard, both Pentium era machines, has never had a problem - except that I'm getting some re-allocation errors on the HD - that system is being replaced this week. The difference is the one with the time-outs is running an older IBM XPW series drive, while the one that never fails is running an even old Seagate Barracuda - one of the original 1/2 height [before they went to 1"] drives] and therefore is about 6 years old. I had to reboot the one with the time-outs because of a user screwup >ME< so it's only been up for 243 days. It's running fairly light duty as a mail server with probably 10-15K messages per day. I've always assumed it was related to the controller/drive interaction as the machines are identical down to the motherboard firmware level, except for the HDs.
