Could you give the actual failure message? Hallo Sometimes I have the same problem (Adaptec 2940u). But it doesn't happen on every reboot. Somewhere in the Suse dist. 4.2 there is a hint to solve the problem but I couldn't find it again. I think it was like this: Give the kernel the boot parameter aic7xxx=noreset. (aic7xxx is the driver for my scsi adapter) Then the scsi adapter will not make a reset again. Hope that's right and will help you.

Could you give the actual failure message? We had a client with a similar problem with one of our cards. Turns out that his sound card wasn't fully honoring the bus reset, and was grabbing the IRQ out from under the Cyclades card. From a power-on start, the system worked fine, but after a three finger salute, or even pushing the reset button, the card didn't work. Something like this would hang your system if the SCSI card suddenly found itself without the IRQ it was set for... and sound cards LOVE to grab IRQ 11. It works with DOS does not mean that there is not a hardware conflict. The DOS drivers probably initialize the hardware differently. Standard procedure is to pull out everything except the minimum necessary to boot (plus the offending card, if not a required card). Add cards until the problem resurfaces. -- ++ | Technical Support Engineer, Cyclades Corporation | | 800/88-CYCLADES (882-9252) or (510)770-9727, x258 | | Maker of High Performance Multiport Serial Cards | | Unsolicited mail ads subject to a $25 handling fee | ++

This is with two flavors of Slacware and with Debian. It seems to be a problem that my SCSI adapter has with Linux in general.

System hangs on SCSI reset (AHA 1522).
Problem: The system hangs when the SCSI bus is reset. Config: Adaptec 1522 SCSI controller Two different motherboards Three different versions of Linux More specifically, I cannot perform a soft reboot from Linux. If, for example, I run 'shutdown -r now' the system will shut down normally, but will hang during the boot phase just after it recognizes the SCSI controller. I can reboot DOS to DOS, but if I am running DOS and reboot to Linux the system hangs in the same place. Shutting off power and then rebooting clears the problem. Any clues or comments?
