IDE tape drive not functioning

[Peter Spikings]

Binary package hint: linux-source-2.6.22

Hi,

My Travan STT3401A tape drive is no longer working after upgrading from Gentoo (2.6.18) - it worked fine before. My secondary IDE controller has a CD drive as master and the tape drive as slave. On boot this appears in the dmesg output:

[ 25.569401] ata2: PATA max UDMA/133 cmd 0x00010170 ctl 0x00010376 bmdma 0x0001b408 irq 15

Then when I try to do anything with the tape drive:

# mt -f /dev/nst0 eject
mt: /dev/nst0: rmtopen failed: Input/output error

with this in dmesg:

I've tried noapic and acpi=off as kernel parameters but they had no noticeable effect other than to stop my network card working!

I'll attach the output of lspci in a moment.

Thanks,

Peter.

Hi,

Is anybody going to look at this? I'm going to be moving the tape drive to another machine with an older kernel very soon so will be unable to provide any additional debugging past that point.

I think the problem lies with whatever presents the drive as a SCSI tape drive instead of using the ide-scsi module. Not sure what is doing that in the new kernel.

Thanks.

Hi Peter,

Sorry for the delayed response. The Hardy Heron Alpha series is currently under development and contains an updated version of the kernel. It would be helpful if you could test the latest Hardy Alpha release: http://www.ubuntu.com/testing . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. We'll keep this open against the actively developed kernel but against 2.6.22 this will be closed. Thanks.

Hi,

Using Hardy alpha 5 server sorted this out.

Thanks for your help,

Peter.
