kernel panic

Description of problem:
I'm getting this kernel panic (see screenshot) when connecting my external USB hard drive, copying a file (from NTFS partition) onto local disk, leaving the nautilus window open (while viewing the remote directory) and hitting "Safely eject drive" in Nautilus.

When I first changed the directory to a local one and then unmounted the partition, the "safe eject" then went ok.

Version-Release number of selected component (if applicable):
Linux kparal 2.6.40-4.fc15.x86_64 #1 SMP Fri Jul 29 18:46:53 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

How reproducible:
2 times out of 2 attempts

Steps to Reproduce:
1. connect external hard drive with ntfs partition
2. copy file
3. leave nautilus window open while viewing the remote directory
4. hit "safely remove drive"

Can you test this build ?

it contains a patch that might fix this issue.

Comment 2 Kamil Páral 2011-08-12 14:10:30 UTC
Thanks Dave, but unfortunately that doesn't help. Kernel panic still occurs.

Comment 3 Dave Jones 2011-08-15 17:48:28 UTC
thanks for testing. Exactly the same trace I assume ?
I'll take this info back to the upstream scsi/block developers.

Comment 4 Kamil Páral 2011-08-16 07:41:54 UTC
It's hard to compare kernel tracebacks, photo by photo, when I don't know anything about kernel tracebacks (i.e. what the important parts are). Lots of characters :)

But they looked very similar, yes. I'll try to reproduce it once again in a few days and compare it more closely.

Comment 5 Fedora Update System 2011-08-16 12:46:28 UTC
kernel- has been submitted as an update for Fedora 15.

Comment 6 Fedora Update System 2011-08-17 01:17:11 UTC
Package kernel-
* should fix your issue,
* was pushed to the Fedora 15 testing repository,
* should be available at your local mirror within two days.
Update it with:
# su -c 'yum update --enablerepo=updates-testing kernel-'
as soon as you are able to, then reboot.
Please go to the following url:
then log in and leave karma (feedback).

Comment 7 Kamil Páral 2011-08-17 13:16:59 UTC
I re-tested with kernel- It does not fix the issue. The trace however seems different. The original says "comm: usb-storage" and the new one says "comm: ksoftirqd/0". But again, I don't know what to look for.

kernel- has been pushed to the Fedora 15 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 10 Josh Boyer 2011-10-11 13:22:09 UTC
Kamil, can you try the kernel and let us know if that resolves the problem?  There is yet another blk fix in that kernel.

Comment 11 Kamil Páral 2011-10-17 09:53:10 UTC
This has been fixed with Thanks!
