https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D285681 Wei Hu <weh@microsoft.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |weh@microsoft.com --- Comment #11 from Wei Hu <weh@microsoft.com> --- (In reply to Mark Millard from comment #9) You are likely hitting the problem introduced by following commit: https://cgit.freebsd.org/src/commit/?h=3D1b9096cd1d2fce1edb7077aebd3512cc61= c54371 It causes arm64 boot hangs on Hyper-V. I heard Andrew Turner has fixed this recently. But I just tried boot from latest main on arm64 VM in Azure and i= t is hitting a different panic with stack like: panic: vm_fault failed: 0xffff000000627fa8 error 1 cpuid =3D 17 time =3D 1743320704 KDB: stack backtrace: db_trace_self() at db_trace_self db_trace_self_wrapper() at db_trace_self_wrapper+0x38 vpanic() at vpanic+0x1a0 panic() at panic+0x48 data_abort() at data_abort+0x28c handle_el1h_sync() at handle_el1h_sync+0x18 --- exception, esr 0x96000004 rib_notify() at rib_notify+0x38 add_route() at add_route+0xc8 add_route_flags() at add_route_flags+0x1bc rib_add_route() at rib_add_route+0x33c ifa_maintain_loopback_route() at ifa_maintain_loopback_route+0xfc in6_update_ifa() at in6_update_ifa+0xa44 in6_ifattach() at in6_ifattach+0x1c0 in6_if_up() at in6_if_up+0x98 if_up() at if_up+0xd4 ifhwioctl() at ifhwioctl+0xc18 ifioctl() at ifioctl+0x8bc kern_ioctl() at kern_ioctl+0x2e4 sys_ioctl() at sys_ioctl+0x140 do_el0_sync() at do_el0_sync+0x608 handle_el0_sync() at handle_el0_sync+0x4c --- exception, esr 0x56000000 KDB: enter: panic [ thread pid 202 tid 100285 ] Stopped at kdb_enter+0x48: str xzr, [x19, #2048] Anyway, 14.0 and 14.1 arm64 image should boot up fine on Hyper-V if you lik= e to try Mark's patch. --=20 You are receiving this mail because: You are the assignee for the bug.=
