>Description:
First, I had NetBSD 9.0/9.1 running on another computer. That computer crashed every 30 days or so for no obvious reason. No logs or kdump were generated. Last month, I put that computer's harddrive into another computer and got there yet another crash after roughly 30 days. This time with some logs.

These crashes always happen when I'm not around, e.g. no particular work-load was running. xset was probably turning the monitor off.
Xorg did not log anything at the time of the crash. There is no custom xorg.conf file.

=46rom a Google search, I learned that this is a common problem on NetBSD.=
The
recommended workaround is switching to uxa acceleration. Uxa acceleration =
works
for a few hours, days or weeks. Eventually, the uxa driver fails for me in
./external/mit/xf86-video-intel/dist/src/uxa/intel_batchbuffer.c with
[ 26933.347] (EE) intel(0): Failed to submit batch buffer, expect renderin=
g corruption: Cannot allocate memory.
I don't see a rendering corruption; this results in multimedia application=

server makes multimedia applications work, again. Here is a segfault of ff=
