Description Michael A. Peters 2005-01-30 20:49:31 UTC

Description of problem:
Only device that had been connected to FireWire was iPod, and it has
been unmounted AND ejected for hours (ejected as in /dev nodes been
removed, no "do not disconnect" message.

I needed to do something in windows, so I rebooted from gnome.
I think I physically disconnected iPod before choosing reboot, but it
is possible I chose reboot and then physically disconnected.

Here's the panic that resulted:

ieee 1394: sbp2: aborting sbp2 command
Test Unit Ready 00 00 00 00 00
Kernel panic - not syncing : drivers/ieee1394/sb2.c:505:
spin_is_locked on uninitialized spinlock c3237ac8

Hardware: A7N8X Deluxe w/ built in FireWire
Additional Belkin FireWire card in PCI slot

Fom lspci:

00:0d.0 FireWire (IEEE 1394): nVidia Corporation nForce2 FireWire
(IEEE 1394) Controller (rev a3)

01:09.0 FireWire (IEEE 1394): Texas Instruments TSB12LV26 IEEE-1394
Controller (Link)

If it matters, the iPod connects to the onboard IEEE 1394 (the TI card
is only there for times when I need to connect a second 6-pin firewire
device, rare)

Version-Release number of selected component (if applicable):
2.6.10-1.741_FC3

How reproducible:
Couldn't Reproduce

Steps to Reproduce:
This has only happened to me once - I've been connecting the iPod for
about a month (Christmas gift)

It has never happened to me again since - I don't know that it still an issue or
not.
