My server went down early this morning. These are the messages that were logged, followed by the SCSI info from boot-time. I had someone at the office reboot the machine, but before he did he said there were a bunch of messages on the screen (these messages), ending with something like "IRQ deadlock detected by CPU 1". The machine is a dual pentium 200 with an Adaptec 2940UW running kernel version 2.0.32. AIC7xxx driver is version 3.2 The general question here is what I need to do to make this machine stable. More specifically, do I have a SCSI driver problem, a SCSI card problem, or a SCSI tape drive problem? I've had some infrequent SCSI timeout messages in the logs the last few days indicating the tape drive as well. (exact messages are available if they're needed for debugging).
