I have recently been encountering some strange problems on a SUSE SLES 8 system. One symptom is that my backups are taking much longer to complete.
Is your backup device a parallel port Iomega ZIP drive, or similar?
I have also recently found the following messages in /var/adm/messages.
I would appreciate any help that is available.

Dunno.

Jun 30 08:49:20 linux kernel: parport0: PC-style at 0x378 [PCSPP] Jun 30 08:49:20 linux kernel: lp0: using parport0 (polling).
Configure your system to use IRQ instead of polling to access your printer port: that alone will make access to the Iomega drive faster (or any other type of drive connected there, and printing as well). Something like this: options parport_pc io=0x378 irq=7,none in your /etc/modprobe.conf.local file or equivalent for your version. Mine report thus: nimrodel kernel: parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE,EPP] nimrodel kernel: lp0: using parport0 (interrupt-driven).
Jun 30 08:49:20 linux kernel: parport0: PC-style at 0x378 [PCSPP]
Notice that the bios configuration of your parallel port (PCSPP only in your case) limits the speed.

You have something connected to your parallel port, and the kernel has tried both imm and ppa drivers, and failed:
As of 31/Aug/1998 Iomega started shipping parallel port ZIP drives with a different interface which is supported by the imm (ZIP Plus) driver. If the cable is marked with "AutoDetect", this is what has happened.
Check if that applies to your setup. Bad cable? Other type of drive?

More details about your system are needed... I can only make guesses. - -- Cheers, Carlos Robinson -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) Comment: Made with pgp4pine 1.76 iD8DBQFCxExitTMYHG2NR9URAgX7AJ9yZw+Mi22B9LfUz+3xUWlq7IXX8gCfbKix D4/y3gbOzOpBlQmboXE0v2s= =lfci -----END PGP SIGNATURE-----
