Re: BUG() in asm/pci.h:142 with 2.4.13

[Christian Hammers <ch@westend.com>]

Hello

Now it crashed again when writing the tape but after writing 1GB to it.
This time I could capture the output of the extra new-queue debugging
output that I enabled in the kernel configuration (this time 2.4.12-ac6).

For the linux-scsi guys: if you need more information please take a look
at my previous posts to linux-kernel (same subject) or contact me directly.

bye,

 -christian-
