Hi all,
I have a rather severe problem.
I have a server which I recently converted over to act as the Domain Controller + File server for a small network of 4 computers. Before the E-Smith server was only running as a Firewall/Gateway.
Now I installed an old SCSI Card (Adaptec AHA-1524 - Using the aha-152x module) and a Sony 9000 (forgotten the full model number) Tape Drive.
Now when the server goes to backup at about 8:30 every night the server comes crashing down. No errors or anything it just ceases to operate.
This is what is showed in the messages log
Jun 22 20:30:00 server kernel: st: bufsize 32768, wrt 30720, max buffers 5, s/g segs 16.
Jun 22 20:30:00 server kernel: Detected scsi tape st0 at scsi0, channel 0, id 4, lun 0

after that nothing is logged until the server is hard booted?
Here is the flexbackup log if youre interested

Come on guys. Does anyone know why this would be happening??
Thanks in advance.

I just troubleshot a very similar problem with my Dell PE2550.
It turned out that my SCSI controllers were sharing interrupts and causing intermittent lockups, always during a backup. Try disabling anything that you're not using so that your motherboard can assign unique IRQ's to all the internal devices and see if it helps. ie com1/com2/lpt1/usb/mouse/ir/etc.

Mine does exactly the same thing that's why I came here hoping for a cure, did you figure it out in the end?

After updating the bios and disabling every device not used, I haven't had a lockup.
