Now I have just realized this: 00:0d.0 SCSI storage controller: Adaptec AIC-7892A U160/m (rev 02) 00:0e.0 SCSI storage controller: Adaptec AHA-2940U2/U2W / 7890/7891 (rev 01) leda:~# lsscsi -Hv [0] aic7xxx dir: /sys/class/scsi_host/host0 device dir: /sys/devices/pci0000:00/0000:00:0d.0/host0 [1] ata_piix dir: /sys/class/scsi_host/host1 device dir: /sys/devices/pci0000:00/0000:00:07.1/host1 [2] ata_piix dir: /sys/class/scsi_host/host2 device dir: /sys/devices/pci0000:00/0000:00:07.1/host2 leda:~# lsscsi [0:0:0:0] disk IBM IC35L018UWD210-0 S5BS /dev/sda [0:0:5:0] cd/dvd TOSHIBA CD-ROM XM-6401TA 1015 /dev/sr0 [2:0:0:0] disk IOMEGA ZIP 250 51.G /dev/sdb Device 00:0e.0 is the 2940, which has nothing hung. Who's to blame ? the bios because is assigns no interupts as no devices are connected to the bus ? Or the kernel that should understand something like 'this device is disabled' ? I can try to change the cdrom to the 2940 and see what happens... Thanks, I will try the patch posted, it looks something like what I said above, disable the device. -- J.A.
