Hello, I've upgraded a RHL 6.2 system to RHL 8.0. The upgrade went without any problems. At first boot the system will not boot, with what seems to be a problem with the aic7xxx driver. The system has an AIC-7896 with BIOS 2.20S1B1 and Mylex DAC1100 RAID controller, BIOS 4.10-41. There are five 36GB IBM disks. No changes were made to the h/w config after upgrading. After the upgrade kernel 2.4.18-14 and 2.4.18-14smp are installed, LILO is bootloader. After identifying the AIC 7896 controller, there is no longer a message saying scsi: 2 hosts as before. Instead it says blk queue c361ee14, I/O limit 4095MB (mask 0xffffffff) and then goes on to probe each device in each channel it seems, and producing a lot of ouput. Kernel Free SCB list: 3 1 0 scsi0: 0:1:0 command already completed aic7xxx_abort returns 0x2002 scsi: device set offline - not ready or command retry failed after bus reset host xxxxxxxxxx After trawling the net for a solution I have tried this: Setting the speed of the devices in the SCSI Select down (to 20). Booting with pci=noapic Booting an smp kernel (this stops at the message: oprofile: APIC was already enabled) None of the above has helped. If I leave the system trying to boot for long enough (all 16 devices on both channels probed I guess), it progesses a bit further until it locks up. I *can* boot using the RHL 8 CD using linux rescue, dmesg shows the same blk queue c361ee14, I/O limit 4095MB (mask 0xffffffff) message twice, then goes on and lets me get into the rescue environment. I find that strange, but hey its a strange world. Is it possible to bring this system back to life? Any help appreciated. -- Mvh Ragnar Wisløff ------------------ life is a reach. then you gybe.
