Description Jeff Potter 2002-10-17 14:57:07 UTC
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:

Comment 3 Arjan van de Ven 2002-10-17 15:02:28 UTC
can you attach your /etc/modules.conf too ?
what does "modprobe aic7xxx" result ?

Comment 4 Jeff Potter 2002-10-17 15:09:20 UTC
% 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.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
