Any suggestions welcomed. Hardware: 2x300MHz PII, 512MB Dell 4300; internal 9GB Seagate system drive; qlogic ISP2100 w 7x18GB FC-AL Seagate SCSI drives in a Eurologic shelf for RAID 5. Software: stock RH6.0, 2.2.5-15smp (.90 raidtools); RAID5 compiled in kernel, autodetect working. Symptoms: Kernel panic: attempt to call schedule() while in interrupt. scsi.c, 1455 Panic happens consistently 20-30 seconds after automatic, very normal appearing RAID initialization sequence startup. Partition drive type is 0xfd, persistent superblock is defined. Unfortunately raid init starts very early in the boot sequence and the machine crashes too early to grab messages I will have to reinstall. Perhaps new /dev/mdX raid initialization should not start in run level 1? I don't have much experience with the qlogic FCAL controller but it seems odd: - No matter what C/H/S values I put in LILO append statement, fdisk only sees 8GB. This is not so with EIDE. ??? - The qlogic firmware sees controller in target 0, 1-8 empty, 9-15 with disks. Controller BIOS enabled or disabled seems to make no difference. Is this usual or maybe Eurologic issue? --
