Subject: Kernel 4.1.5 not stable - crashes

Hello,

I'm having big problems with Fedora FC22 kernel 4.1.5 (happened with all 
tried kernels 4.1.x from FC22) which is not stable at all. At the 
nightly backup jobs (database dumps, rsync via ssh, etc.) maschine 
crashes reproduceable at every night with the stack trace below. Message 
repeats on different CPUs in around 1~10s with same message.

Kernel 4.0.8 from Fedora FC22 works well with long uptimes, also 
previous kernel versions are highly stable. Kernel 4.1.4/4.1.5 had a lot 
of RAID fixes so I tried it again but it didn't help. So something 
critical must be different from 4.0.8 to 4.1.2 and later.

I'm running 2 RAID5 volumes with each LVM and cryptsetup above. After 
the crash RAID does a resync.

Machine:
- Mainboard: ASUS - M3N-H HDMI with latest BIOS
- CPU: AMD Phenom II X4 940 Black Edition, 4x 3.00GHz, boxed (HDZ940XCGIBOX)
- NIC: HP Broadcom Netxtreme Gigabit PCIe Netzwerkkarte 482914-001 (BCM5761)

If you need further information please let me know.

Any ideas?

Thank you.

Ciao,
Gerhard
