I never get oops logged to /var/log/* if I am lucky, I can catch them from the console before it blanks. This apparently has something to do with mounting root on /dev/md0. I even tried putting /var/log on the aha1542 as a mount, but I am guessing that beacuse the root file system goes haywire, the mounts become inaccessible also. And yes, I use the latest driver. > You should try lowering this to 8.

Though according to the docs, they can actually go upto 31 total commands deep total and they hum right along with the other devices. Of course the Asus PCI-SC875 is only 12 commands deep - the BusLogic BT-958, I don't know. The drives have different firmware levels. I recall, the firmware levels to be wa6e for six of them (that came from a distributor channel) and wa3e for the other three (that came directly from IBM). That difference in firware levels has always annoyed me, I don't know if there is any way to upgrade the firmware on those drives. > You know that you're not getting the latest driver at 2.1.42?
