Distribution: Gentoo Linux Hardware Environment: Athlon, MSI-Board, 2 Adaptec 2940 UW-Controllers Problem Description: The System hangs after initialising the first controller. The last lines are: scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36 <Adaptec 2940 Ultra SCSI adapter> aic7880: Ultra Wide Channel A, SCSI Id=7, 16/253 SCBs The system hangs after this message. On 2.4.x the second controller is initialised without problems. Steps to reproduce: Unkown, but 2.6.0 also had the sam problem. The system just hangs without any error messages.
Removing one controller didn't help - the system still freezes at the same point so the error seems to be somewhere else. Adding logging options for SCSI also didn't bring any new messages or hints. Ok, here is the data of the used hardware: MSI K7T266 Pro2 (VIA VT8366A North Bridge, VT8233 South Bridge) 768 MB RAM Athlon 1.8 GHz Matrox MGA 400 3 IDE-Drives (which are all detected) 2 Adaptec 2940 UW (BIOS V2.20.2 and V 1.34.3) with 4 drives attached to each controller Alex
Adding "pci=noacpi" to the kernel while booting removed the error, the system was booting after adding it. So the error must be a conflict with acpi and scsi. Alex
Is this problem without "pci=noacpi" still present in kernel 2.6.12.2?
