Clicking the power hardware button did not trigger the usual shut down screen during this particular lockup case; clicking the power button twice (assuming it might just be the gfx that had locked-up) had no effect; finally I held down the power button for some seconds until the power led flashes and then the hard powers off.

None of the three entries allow invoking the details view or raise their palette so can not be erased via the Sugar Journal UI. The three corrupt entries will be an entry for Browse where I visited ASLO to download telescope and then quit Browse; the downloaded Telescope-12 bundle; and the instance entry for the Telescope that was running when the XO locked up.

I tried to reproduce with Telescope, and I get an oops/hang as well.
The same oops is already filed as https://dev.laptop.org/ticket/11128.

Using a serial console for logging may show if it is a panic/crash or
a hang (like a very busy loop). If you unbricked your XO-1.75 with an
other Linux system, you should be able to use minicom to capture a log
in a similar way.

After starting minicom, press CTRL+a,z (press CTRL+a together, release
them, press 'z') to get in the minicom help/menu. Pressing 'l' will
ask you for a filename, I'd use samething like
xo-1.75-camera-issue.log. After pressing return, everything will be
saved. Now turn on the XO and reproduce the issue.

When you encounter the panic/hang again, press CTRL+l in minicom to
close the logfile and exit minicom.

I'll try this as well, but am still running build 882 which may be
differnt than build 883 in this respect.

Good luck,
Niels
