Package: powersaved Version: 0.14.0-8 Severity: normal I've got MAX_CPUS_ONLINE=1 in scheme_powersave, and I managed to crash the kernel lastnight when rapidly plugging and unplugging power to my laptop[1] (on timescales of a second or so). I have no logs because it was a very hard crash (alt-sysrq S-U-B didn't do anything), so can't prove it was because the number of CPUs was changing before things settled down, but it seems reasonable. I wonder if powersaved should somehow work out things have settled before trying to change the state again? 'course, this is really a kernel bug (good luck finding the real cause of it though), but a (configurable?) timeout in powersave wouldn't hurt.
