Any help to solve the annoying problem or hints are greatly appreciated. Actually i'm using a vanilla linux kernel (2.4.21) with the aic79xx-1.3.10 source unpacked on the right place in the kernel sources. The kernel is compiled with SMP support (a complete .config from the running kernel is available at http://laokoon.in-berlin.de/~beutin/kernel-config.gz). Three disks are connected to the first channel of the onboard Adaptec AIC7902 of the Intel SE7501HG2 board (/proc/scsi/scsi): Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: IC35L036UCPR15-0 Rev: S70H Type: Direct-Access ANSI SCSI revision: 03 Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: FUJITSU Model: MAP3367NC Rev: 0105 Type: Direct-Access ANSI SCSI revision: 03 Host: scsi0 Channel: 00 Id: 02 Lun: 00 Vendor: FUJITSU Model: MAP3367NC Rev: 0105 Type: Direct-Access ANSI SCSI revision: 03 Host: scsi0 Channel: 00 Id: 06 Lun: 00 Vendor: ESG-SHV Model: SCA HSBP M15 Rev: 0.10 Type: Processor ANSI SCSI revision: 02 The first disk works perfect and the system starts up fine (only the first disks file systems are in /etc/fstab). dmesg output looks ok (is pretty long, You can find it on http://laokoon.in-berlin.de/~beutin/dmesg-after-boot.log.gz) After accessing one of the FUJITSU disks the system hangs and the dmesg output shows a lot of "DevQ(0:?:0): 0 waiting" and card state dumps (the output is long, You can find it on http://laokoon.in-berlin.de/~beutin/dmesg-mount-try.gz). What can i do? Do i have any chance to get a stable system with all three disks useable? Thanks for reading and any suggestions!
