with kernel 2.4.9-ac9, the problem remains the same, but i have
finally been able to capture an oops message. "capture" here means
copying the whole shit from the log console and typing it back in
again at ten past midnight, so excuse minor inaccuracies...

the syslog messages just before the oops were:

hda timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hda status timeout: status=0xd0 {busy}
hda: drive not ready for command
hda: ATAPI reset complete
hda: irq timeout: status=0xd0 {busy}

and now, the oops:

ksymoops 2.4.0 on i686 2.4.9-ac9

Warning (compare_maps): mismatch on symbol usb_devfs_handle ,
usbcore says e2a53320,
/lib/modules/2.4.9-ac9/kernel/drivers/usb/usbcore.o says e2a52e40.

<0>Kernel panic: Aiee, killing Interrupt handler !

2 warnings issued. Results may not be reliable.


here's my system config again:
dual p3/600, 512mb ram,
asus p2b-ds mobo w/ onboard aic7xxx scsi, pci scsi controller
symbios (disabled, module *not* loaded when the oops occured), one
scsi cdrom and one 4gig scsi hd connected to the adaptec onboard,
one disk hdc connected to onboard IDE #1 (master), and the offending
cd burner hda, connected to onboard IDE #0 (master), and running in
scsi-emulation mode.

hope the oops will be useful to someone...

please keep me cc:ed on replies.

all the best,


Jörn Nettingsmeier
