timeout in wait_for_sysfs

timeout in wait_for_sysfs

[Tom Holroyd]

2.6.9-1.678_FC3, yum-updated as of 11/20, including new udev and kernel.

I plugged this USB flash disk in (bus 3 dev 2):

Bus 004 Device 001: ID 0000:0000
Bus 003 Device 002: ID 090a:1941 Trumpion Microelectronics, Inc.
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 002: ID 058f:9254 Alcor Micro Corp. Hub
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

It got successfully mounted, type vfat.  I umounted it, and removed the device.
Then I plugged it in again, and got these timeouts.  100% reproducible, also
with the stock FC3 kernel.

Other users reported the same problem here. You may try:
  eject <device>

before you unplug the device.

Do you have anything running which has files opened on the device,
something like fam?

OK, I su'ed (eject didn't work otherwise), and said
'eject /media/NO_NAME' -- it unmounted, and I unplugged it,
then plugged it back in.

Same error as before.

No; it doesn't let me unmount it if I do.

I found that if I rmmod the usb_storage, and scsi modules, then 
it does NOT give me the error when I plug it in the second time.  
It didn't automount right away, though.  I think the disk-mounter 
panel applet mounted it about 10 seconds later...

Yeah, all I need to remove is usb_storage, and when I plug it in 
again it's fine.  Automounts OK too if the scsi modules are still 
in there.

You may try "eject /dev/sda". Some people reported that this was
working.

Yes, seems like a kernel bug. There is currently no fix for it. You may
look here:
