https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229167 --- Comment #23 from pete@twisted.org.uk --- (In reply to Dexuan Cui from comment #21) So, I rebuilt with CURRENT, and it booted fine on UFS. Then I rebooted it a couple of times, and the third time it did this: mlxen0: Ethernet address: 00:0d:3a:2f:f9:61 <4>mlx4_en: mlx4_core0: Port 1: Using 4 TX rings mlxen0: link state changed to DOWN <4>mlx4_en: mlx4_core0: Port 1: Using 4 RX rings <4>mlx4_en: mlxen0: Using 4 TX rings hn0: link state changed to DOWN <4>mlx4_en: mlxen0: Using 4 RX rings <4>mlx4_en: mlxen0: Initializing port Fatal trap 12: page fault while in kernel mode cpuid =3D 2; apic id =3D 02 fault virtual address =3D 0x1d8 fault code =3D supervisor read data, page not present instruction pointer =3D 0x20:0xffffffff80c6a3ea stack pointer =3D 0x28:0xfffffe00004bb950 frame pointer =3D 0x28:0xfffffe00004bb960 code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 0 (vmbusdev) [ thread pid 0 tid 100105 ] Stopped at vrefact+0xa: cmpl $0x4,ll+0x1b7(%r14) db> Hmmmm... thats the same (UFS based) machine being rebooted, no changes, so = it look unpredictable :-( Am going to try it again and also try with ZFS if I = can, but it does look like it shows up in CURRENT, just not every time. --=20 You are receiving this mail because: You are the assignee for the bug.=
