This is not convenient, because:
- requires an additional computer.
- after the GPU freezes, the chances of correctly restarting the
computer tend to zero.
For me, as a bug hunter, it would be more convenient if all the dumps
were automatically dropped before resetting the GPU to specified
directory.

But thanks anyway.
Here is a new bug report: https://bugs.freedesktop.org/show_bug.cgi?id=110605
