X260 has always been problematic with reboots, not 100% of the time (in
particular a reboot shortly after boot seems more likely to work) but
very often. The only thing I've seen that improved things there is
kettenis' "EFI runtime services on amd64" diff.

This problem with the (~6 years older) T410 that just recently started
happening sounds like something different.
