https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=253335 Mark Johnston <markj@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |imp@FreeBSD.org --- Comment #10 from Mark Johnston <markj@FreeBSD.org> --- The problem appears to be with this commit: https://github.com/qemu-bsd-user/qemu-bsd-user/commit/63d5d4f649f44f8e3d9105dec40a354d92a19550 That check is indeed needed. qemu relies on delivery of SIGSEGV to detect self-modifying code so that it can update its translation cache accordingly. This will manifest as a page fault, so ksi_trapno is T_PAGEFLT == 0xc on amd64. -- You are receiving this mail because: You are on the CC list for the bug.home | help
