Title:
APM Mustang board kernel crashes when running Ceph
Status in linux package in Ubuntu:
Won't Fix
Bug description:
Hi,
We've been running Ceph on 4 APM Mustang boards within Linaro, running stock
Ubuntu Utopic (problem occurs with Trusty too).
Essentially when I place the network under heavy load (by writing data
to a Ceph filesystem backed by 3xOSDs), I experience kernel crashes.
I've harvested a few backtraces from the serial port and will paste
them below as separate comments.
I think the problem lies in the xgene driver, but I don't know enough
to resolve where this problem is happening.
Cheers,
--
Steve
