[Benjamin Drung <bdrung@xxxxxxxxx>]

The output of dmesg shows "mmc2: Timeout waiting for hardware
interrupt." The mmc2 is a SanDisk Extreme Pro microSDHC 16GB card which
was used as system storage.

I replaced the microSDH card with an other one. Since then there has
been no further occurrences of this bug. The SanDisk Extreme Pro
microSDHC card works fine in my mp3 player and when connected to the
desktop computer.

Does the microSDHC card trigger a software bug or is this an
interoperability hardware issue?

Title:
  [ARM] Crashes under load

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  The Wandboard Quad crashes under load. This can be triggered by
  running "apt-get upgrade" or a scripts that converts a git repository
  to bzr, for example. It does not crash every time, but often enough to
  reproduce the crash. Attached the output of dmesg after the crash.
