[Pkg-utopia-maintainers] Bug#881352: kernel crash while upgrading udisks2

[Jiri Palecek]

Hello,

I got a similar crash as well (submitted through kerneloops). BT:

[41523.486054] ---[ end trace 3dbeb3dfc6223f18 ]---

However, I wonder if this is the same as https://bugs.debian.org/876712. 
The backtrace points to softirq processing and rcu as well. I've got 
more of such backtraces (one of them, however, points to an assertion 
failure in rcu code). However, the problem seems sporadic in nature 
(some race condition causing a memory error?) and hard to reproduce.

Please let me know if I can help in any way.

Regards
