Yes. Sometimes within a minute of resuming. Typing stuff into evolution seems
to help with triggering this. It's all a bit mysterious, but this message
alone frooze my laptop a few times. Seriously!

Lazy question: how does one determine the first and last commit inside a merge
request? Can I simply do
    good   a2d635decbfa9c1e4ae15cb05b68b2559f7f827c^
    bad    a2d635decbfa9c1e4ae15cb05b68b2559f7f827c

for git bisect?

I usually use one of the ThinkPads from my embarrassing pile of outdated
hardware to do nasty bisects, but I'm not about to loose any income if my much
appreciated XPS 13 is out of order for a while.

Thanks,
