from Alan W. Irwin
This last stability test lasted only 17.5 hours before the loc=
kup. See the
latest attached tarball for the relevant log files (which capture everything
during this short up time) and dmesg output. As far as I can tell there is
nothing in those log files relevant to the lockup, e.g., no burst of null a=
scii
characters like what occurred in the log files for the previous experiment.
There are some segfaults associated with a cron task I have configured every
morning starting at 4:32, but those always occur for that task (which is a
complete build and test of CMake) so I don't think they are relevant.
The actual lockup today happened with one inactive desktop running on the
X-terminal and one active desktop running on the new box. (I was editing a
file with Emacs.) Also, the symptoms of this lockup were more severe, i.e.,
ping
did not work from the X-terminal to the new box. But as always there was no
way to shut down the new box properly so I had to do that with the reset
button.
Since I bought the new box in May remote access from an X-terminal has only
locked up twice (one of those detailed here), and after a relatively long
period of time. So tests where the X-terminal use is the only way to access
the new box seems in general much more stable than direct use (as in the
present case with such a short time before the lockup). And I haven't tried
sole use of the X-terminal for a while now, and that may be completely stab=
le
with the new kernel. So my conclusion remains that the problem is associat=
ed
with the Debian Buster graphics stack (and likely also the very latest grap=
hics
stack if someone will do some up time tests for modern AMD graphics cards f=
or
that stack) used to display and control the RX 550 card on the new box.
I have now started a new test (as of 9:08:19 today) with all graphics stack
versions and kernel parameters the same as for the previous test in hopes t=
hat
when the inevitable lockup comes the log files will be more informative.=20
Please let me know if you have some other experiment you would like me to t=
ry.
