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
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.
Thanks Dave, but unfortunately that doesn't help. Kernel panic still occurs.
thanks for testing. Exactly the same trace I assume ?
I'll take this info back to the upstream scsi/block developers.
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.
kernel-188.8.131.52-0.fc15 has been submitted as an update for Fedora 15.
* 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-184.108.40.206-0.fc15'
as soon as you are able to, then reboot.
Please go to the following url:
then log in and leave karma (feedback).
I re-tested with kernel-220.127.116.11-0.fc15. 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 panic with 18.104.22.168-0
kernel-22.214.171.124-0.fc15 has been pushed to the Fedora 15 stable repository. If problems still persist, please make note of it in this bug report.
Kamil, can you try the 126.96.36.199-0.fc15 kernel and let us know if that resolves the problem? There is yet another blk fix in that kernel.
This has been fixed with 188.8.131.52-0.fc15.x86_64. Thanks!
