Build machine updated from r319689 to r319733 OK; smoke test was uneventful.
Laptop updated similarly, but smoke test was a little more "interesting". Turns out that laptop gets to multi-user mode OK... if I disable starting xdm, devd, and hald. But then, issuing "service hald onestart" generates the panic in question -- at r319733. At r319689, xdm & friends worked fine. I have placed copies of the /var/crash/*.6 files in <http://www.catwhisker.org/~david/FreeBSD/head/hald/> -- along with gzipped copies, as well. (It's residential DSL in the US, so there's not a huge amount of bandwidth.) I get the impression that something (ini hald) was trying to use the freebsd11 version of stat(), and Something Bad happened: panic: mtx_lock() of spin mutex (null) @ /usr/src/sys/kern/sys_socket.c:305 cpuid = 7 time = 1497011454 KDB: stack backtrace: db_trace_self_wrapper() at 0xffffffff803a461b = db_trace_self_wrapper+0x2b/frame 0xfffffe0c268ff600 vpanic() at 0xffffffff80a1f94c = vpanic+0x19c/frame 0xfffffe0c268ff680 kassert_panic() at 0xffffffff80a1f7a6 = kassert_panic+0x126/frame 0xfffffe0c268ff6f0 __mtx_lock_flags() at 0xffffffff809fedfe = __mtx_lock_flags+0x14e/frame 0xfffffe0c268ff740 soo_stat() at 0xffffffff80a8f8f0 = soo_stat+0x60/frame 0xfffffe0c268ff770 kern_fstat() at 0xffffffff809cb378 = kern_fstat+0xa8/frame 0xfffffe0c268ff7c0 freebsd11_fstat() at 0xffffffff809cb28d = freebsd11_fstat+0x1d/frame 0xfffffe0c268ff930 amd64_syscall() at 0xffffffff80e31fb4 = amd64_syscall+0x5a4/frame 0xfffffe0c268ffab0 Xfast_syscall() at 0xffffffff80e12eab = Xfast_syscall+0xfb/frame 0xfffffe0c268ffab0 --- syscall (189, FreeBSD ELF64, freebsd11_fstat), rip = 0x801b4973a, rsp = 0x7fffffffe988, rbp = 0x7fffffffea20 --- KDB: enter: panic Note: the hald in question was built under FreeBSD stable/11 (as are all my ports); I noted the existence of, and installed, ports/misc/compat11s before (re-)creating the crash. (And yes, the ports that have kernel modules get the kernel modules rebuilt on head every time I rebuild the kernel on head.) With the caveat that I actually use the laptop in my day-to-day activities, I'm happy to try various combinations of patching, testing, and reporting results. Peace, david -- David H.
