Devices we're not getting their interrupts and hence never get past SCSI disk detection. Try booting the kernel with the "noapic" option so all interrupts are on the first processor (the way a UP kernel would run). You'll still have all processors for running processes. Not the most efficient setup, but a good workaround until the APIC related interrupt problems are fixed. Since the system won't boot for you to run dmesg, boot with 'console=ttyS0,57600' option (assuming kernel has serial port console support built in) and capture all the boot messages by connecting a terminal to first serial port on the system at 57600 8n1. Then send the captured output to this list so folks can examine the APIC detection and setup results. -Eric Malkowski Nerijus Baliunas wrote: > Hello, > > Both RH 2.4.18-5 and 2.4.19 SMP kernels cannot boot - Adaptec > AHA-3960D (aic7xxx) cannot detect disks.
