Sudden restart

[grahamperrin]

hello-12.1-RELEASE-0a2ed28-amd64.iso (202012301349)

Sudden blackout and restart not long after taking the screenshot at #23 (comment)

Should I assume a kernel panic?

I half-expected an opportunity to bt (but not a core dump).

Environment

HW probe of HP EliteBook 8570p #60d9540d35

Booted from Verbatim STORE N GO s/n 17071802004381

After the event (with a non-helloSystem):

I have never experienced sudden restarts so far. Let's watch this.

Might also want to try 13-CURRENT based builds for comparison (once they become available again).

Thanks. If a kernel panic does occur, should I expect a 'drop out' to a command line? Where bt might produce a backtrace.

Incidentally re: ncw/stressdisk#14 there's the possibility of a drive firmware issue affecting s/n 17071802004381.

With an earlier helloSystem image, the same drive featured in a non-reported boot failure (I/O errors, IIRC) with the drive in one of the rear ports of the Ergo Vista 631.

For the incident at #70 (comment) above I recall beginning (or aiming) to experiment with the global menu for Falkon very shortly before the blackout, so for what it's worth, I wondered about a DRM issue.

Rewind to a few minutes earlier, I recall trying to get Spectacle to recognise Filer as a handler to open the location of a saved screenshot.

When a kernel panic occurs, then I think the system restarts.

[grahamperrin]

No other panic observed, with any medium.
