Nice)
Im trying to find the reason why goroutines fails after SIGURG, which is sent
by preemptive scheduler. it looks like sometimes pc is 0, that means cpu
context is broken after sigreturn.

btw1, im trying to run tools/test/avx_sig test, it fails on Ubuntu 22.04, and
it looks like avx registers is not preserved across context switch. I don't see
any Linux kernel config options for avx registers which is turned off in Ubuntu
22.04. Do you know anything about that?

btw2, could you please check arm64 also?
