--- Comment #96 from Don Lewis <truck...@freebsd.org> --- (In reply to Nils Beyer from comment #91) Since the IRET instruction seems to play a factor in this problem, and it is supposedly microcoded, I'm hoping that a microcode fix is possible for it. I would not expect this to fix problems found by ryzen_segv_test since that code does not use signals, so those processes should not be executing the signal trampoline code that my patch relocates. It's curious that disabling SMT fixes that problem for you. Can you try running ryzen_segv_test under "cpuset -l 2-15" to see if avoiding running the test on the core that handles interrupts makes a difference? -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
