Right now I'm running 13.1 if I enable any of my E cores I get UFS corruption everywhere so I've had to have these disabled. There is a ticket https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261169 which I just updated as I'm still having issues. > hwpmc(4) also does not differentiate P and E cores, and since they have > different counters, it means that only few universal architectural > counters are usable, which are sufficient for basic profiling though. > > There were some stability issues reported, but were solved by either > FreeBSD or BIOS update, so still not really diagnosed AFAIK. I've run into this in my situation some BIOs updates cause constant reboots especially when playing video. I also have serious audio issues with continous popping that I've been unable to solve there is a ticket for that as well: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263385#add_comment I'll give CURRENT A shot again in the next day or two to see if this is all fixed thanks for the update!
