Created attachment 301053 [details] Some logs of the kernel when it oops'd Using gentoo-sources, linux-3.2.1-gentoo-r2, I get a kernel oops when I eject my sd card, after using it normally (mount, use, unmount, eject). I am attaching my kernel .config, as well as two examples of the kernel panic/oops from /var/log/messages
Created attachment 301055 [details] Another example of oops

Note that this issue happens with kernel=3.2.5 as well, but not kernel<=3.0.6
Note that this problem does not happen when virtualbox drivers are not loaded. The following links also address this issue http://marc.info/?l=linux-scsi&m=132388619710052 http://marc.info/?l=linux-scsi&m=132909845126932&w=2
Fedora bugzilla has this too https://bugzilla.redhat.com/show_bug.cgi?id=754518
Sorry, it does happen still (even without vbox drivers)
There is a patch that was written by Jun'ichi Nomura for the 3.3 kernel which fixes this issue. I have tested it with 3.3-rc5. The patch is available here: https://lkml.org/lkml/2012/2/22/1 In that same mailing list thread, Dave Jones posted a backport of the patch to the 3.2 kernel. I have tested that patch with 3.2.1-gentoo-r2 and it also works. I am attaching the 3.2 backported patch to this bug-ticket as well.

Comment on attachment 303761 [details] Dave Jones backport of Jun'ichi Nomura This fixes the issue I experienced with ejecting the SD card crashing/oopsing my kernel, it is a modified version of a linux-3.3 patch proposed by Jun'ichi Nomura
The referenced patch appears to be in kernels >= 3.3.0. Can you please test with a later kernel and post the results.
3.2.12 from the gentoo portage tree is what I run now, didn't need to be patched, I think the code was merged upstream by this version. I will try something newer next week and post the results. Cheers, Naveen
So, after testing, it seems the bug is also resolved in gentoo sources for the linux 3.4.3 kernel
Thanks for testing
