Thanks. Reformatted ticket description to meet trac coventions, improving readability.

Reproduced symptom.

Diagnosis: this is due to diag-switch? being left set after memtest is stopped. When diag-switch? is set, the default boot is via network. The default network name is OLPCOFW.

Fixed in svn 3564 by saving and restoring the value.

Test build: http://dev.laptop.org/~quozl/q7b16jc.rom

Test case:

  • type memtest, press enter,
  • press enter once more so that only one cycle of test is run,
  • once the test has completed, try to boot, the expected result is to boot into Linux.

Will be in next release.
