I've managed to isolate this to the fwts "uefirtmisc" test:
$ sudo fwts uefirtmisc
Running 1 tests, results appended to results.log
Test: UEFI miscellaneous runtime service interface tests.
Test for UEFI miscellaneous runtime service interfaces. 1 passed, 5 skipped
Timeout, server 10.1.11.176 not responding.e service interfaces. : 33.3% |
(That last line is partially overwritten by the SSH termination
message.) At 33.3% through that test, the system spontaneously reboots.
None of the other fwts tests causes any problem.
Oddly, the problem disappeared briefly during my testing. This occurred
just after I removed the 4.4.0-109 kernel, and a run of fwts produced a
message about it being unable to run some tests because it couldn't
parse EFI data, but that a reboot should fix the problem. (Sorry, I
didn't save the exact wording of the message.) I suspect this was
related to EFI variable storage and garbage collection. When I rebooted,
the problem reappeared.
Some further notes:
* The system is rather old (we got it in 2009).
* The system is running the latest firmware, version 6.4.0, released in 2013.
* The UEFI version is rather old (2.1.0).
* It's booted in UEFI mode (of course).
I'm going to try re-creating this problem with a Dell T110 of similar
vintage. For the moment, I'll leave lucuma, the system with the problem,
in its current Ubuntu 14.04 configuration. I can run further tests as
directed. As this looks like a kernel bug, or possibly a bug in fwts,
I'll mark this as "invalid" for plainbox-provider-checkbox.
** Changed in: plainbox-provider-checkbox
