I don't really know how reproducible it was.

It was the first time I saw that kind of hang, I have that laptop for a long
time, always been running linux on it, probably more than 7 years.

Display went black for a few secs, and then I saw the drm output in dmesg.
After that it was having the same kind of black display upon launching vlc, it
stayed black until I ctrl-Q'ed it in the blind...

I still have that kernel around, I'll reboot into it and see if it reproduces.
