wait_for_sysfs for USB key
When I plug in my USB key I get the following :-
wait_for_sysfs[8695]: either wait_for_sysfs (udev 039) needs an update to handle the device '/devices/pci0000:00/0000:00:10.0/0000:02:00.0/usb1/1-2/1-2.1/1-2.1.1/1-2.1.1:1.0' properly (no bus device link) or the
sysfs-support of your device's driver needs to be fixed, please report to <[email protected]>
This is with Fedora Core 3, patched with the 678_FC3 kernel, hotplug-2004_04_01-8.
Can I configure something to stop it, or does this need adding to some sort of config?
Thanks,
Rob

No, unfortunately not with an unmodified package. Some people reported this and is seems like a kernel bug. Can you confirm, that /sys/bus/usb/devices/* is empty? This is probably causing the failure.

No the directory has got several entries which looked they were created when I was plugging in the key. Interestingly the first time I plug the key in it works, it's only after I've unmounted and then try and mount it again, then the above message appears and all USB activity stops and the haldaemon goes into an uninterruptable sleep and only a reboot seems to cure it. Disabling the daemon gives me back the old behaviour of mounting the key manually and continues to work no matter how many times I plug/unplug. As you say with the haldaemon locking up I wonder if its a kernel bug.

Ok, than it's a different issue. We've got reports for an empty bus directory which obviously leads to this kind of message.

What happens if you use "eject" after the umount? Does this work.

Yes! That actually works better. The daemon doesn't hang and the message is not produced. It doesn't always remount properly, but I can always manually mount it myself whereas if I don't do the eject then I have to do a reboot to continue using the USB bus.
What does this point to? I was going to trace the daemon to see if I can find out why it's going into an uninterruptable sleep.

This is most likely a kernel bug; you may look at this Red Hat bug
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id6255
which provides a minimal program to reproduce it.
Thanks,
David
