Description Jan Smout 2016-05-20 10:36:13 CEST 
When removing a ext2 formatted usb stick a kernel Oops is triggered.

My guess is that it is caused by this kernel bug:
https://bugzilla.kernel.org/show_bug.cgi?id=101011

For extra info: after the kernel Oops, executing sync will hang the sync process indefinitely (reboot  required). Not really a surprise with this class of bugs.


Version-Release number of selected component (if applicable):
kernel-server-4.1.15-2.mga5.i586.rpm

How reproducible:
Always

Steps to Reproduce:
1. insert ext2 usb
2. mount it (if not auto mounted)
3. remove the usb stick (without umount)



kernel-server-4.4.11-1.mga5-1-1.mga5.i586.rpm solves the issue. This is expected because the bug was corrected in 4.2.1 (according to the kernel bug report above).


Question: When will updates_testing be released?

I assume that bug 18031 will be re-used for the 4.4.11 update. If it isn't reused, with luck a link to the new report will be given when it gets closed.

It was never released, now 4.4.13 is being tested, see bug 18688

Depends on: 18031 => 18688
