debs-1554635.tar.gz. The subdirectory android-mir-1554635 contains the

attached branch to lp:mir, and its looking like it'll ride along in
0.20.3 mir release.

Attached a branch that will at least ignore the exception. Without being
able to reproduce myself (mir team doesn't have a turbo) or without
seeing dmesg and logcat, its hard to tell if masking the exception is an
appropriate response. Best guess though with information at this point
in time is tha
@Lorn, could you collect the logs from /system/bin/logcat and dmesg when
this happens? This would help figure out if its a resource leak or some
other transient driver problem that we could potentially fix or ignore.

necessary?
This could be a system resource exhaustion issue.
