Upgrading from 2.4.18-5smp to either of the latest errata kernels (2.4.18-10smp or 2.4.18-17.7smp causes scsi tape to stop functioning. % mt -f /dev/st0 status /dev/st0: No such device rebooting back to the 2.4.18-5smp kernel fixes the problem. No other changes were made to the box. 7.3 was installed fresh (ie, not an upgrade install on 7.2). Booting into the counterpart non-smp versions produces the same results. On booting the errata kernels, /proc/scsi/scsi contains: Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: DELL Model: PERCRAID RAID5 Rev: V1.0 Type: Direct-Access ANSI SCSI revision: 02 On booting the -5 kernel (stock from CD), /proc/scsi/scsi contains: Attached devices: Host: scsi0 Channel: 00 Id: 06 Lun: 00 Vendor: ARCHIVE Model: Python 06408-XXX Rev: 8130 Type: Sequential-Access ANSI SCSI revision: 03 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: DELL Model: PERCRAID RAID5 Rev: 0001 Type: Direct-Access ANSI SCSI revision: 02 dmesg logs for both 2.4.18-5smp and 2.4.18-17.7smp are attached. diffing the 2 shows a few things, including in the errata kernels: < Red Hat/Adaptec aacraid driver, Oct 8 2002 < AAC0: kernel 2.1.4 build 2951 < AAC0: monitor 2.1.4 build 2951 < AAC0: bios 2.1.0 build 2951 < AAC0: serial 0a2401d0

can you attach your /etc/modules.conf too ? what does "modprobe aic7xxx" result ?
% modprobe aic7xxx % (modprobe prints nothing, first time I ran it, it took ~10 seconds.) % lsmod | grep aic aic7xxx 129632 0 (unused) scsi_mod 108048 3 [aic7xxx aacraid sd_mod] % cat /etc/modules.conf #alias parport_lowlevel parport_pc alias eth0 eepro100 alias eth1 eepro100 alias scsi_hostadapter aic7xxx alias scsi_hostadapter1 aacraid alias scsi_hostadapter2 aacraid #alias usb-controller usb-ohci Originigally, 'alias scsi_hostadapter aic7xxx' was commented out. I played with uncommenting it today while debugging.
