Hello, While upgrading from source my 13-CURRENT box from ALPHA1 to BETA1, I got the following crash on make installworld. Fatal trap 12: page fault while in kernel mode cpuid = 1; apic id = 01 fault virtual address = 0x30 fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff8034d5b0 stack pointer = 0x28:0xfffffe00c8204600 frame pointer = 0x28:0xfffffe00c8204640 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 65294 (fsck_ufs) trap number = 12 panic: page fault cpuid = 1 time = 1613467739 #16 0xffffffff8034d5b0 in g_slice_access (pp=0xfffff80003ca5100, dr=1, dw=0, de=0) at /usr/src/sys/geom/geom_slice.c:127 #17 0xffffffff8034e6e4 in g_access (cp=0xfffff80003c82e00, dcr=<optimized out>, dcr@entry=1, dcw=<optimized out>, dcw@entry=0, dce=dce@entry=0) at /usr/src/sys/geom/geom_subr.c:1042 #18 0xffffffff8034698f in g_dev_open (dev=<optimized out>, flags=<optimized out>, fmt=<optimized out>, td=<optimized out>) at /usr/src/sys/geom/geom_dev.c:442 #19 0xffffffff80342e46 in devfs_open (ap=0xfffffe00c82047a0) at /usr/src/sys/fs/devfs/devfs_vnops.c:1290 #20 0xffffffff806bb05c in VOP_OPEN_APV (vop=0xffffffff80863e20 <devfs_specops>, a=a@entry=0xfffffe00c82047a0) at vnode_if.c:436 #21 0xffffffff804bef1e in VOP_OPEN (vp=0xfffff80003cdc000, mode=1, cred=0xfffff800029d4420, td=0x0, fp=0xfffff802a7208140) at ./vnode_if.h:220 #22 vn_open_vnode (vp=vp@entry=0xfffff80003cdc000, fmode=fmode@entry=1, cred=<optimized out>, cred@entry=0xfffff80002993700, td=<optimized out>, td@entry=0xfffffe00c8149300, fp=<optimized out>) at /usr/src/sys/kern/vfs_vnops.c:411 #23 0xffffffff804bead0 in vn_open_cred (ndp=ndp@entry=0xfffffe00c8204970, flagp=<optimized out>, flagp@entry=0xfffffe00c8204a94, cmode=<optimized out>, vn_open_flags=vn_open_flags@entry=0, cred=<optimized out>, fp=0x7) at /usr/src/sys/kern/vfs_vnops.c:318 #24 0xffffffff804be6ad in vn_open (ndp=0xfffff80003ca5100, ndp@entry=0xfffffe00c8204970, flagp=0xfffff800029d43c0, flagp@entry=0xfffffe00c8204a94, cmode=0, fp=0xfffff800029d4420) at /usr/src/sys/kern/vfs_vnops.c:193 #25 0xffffffff804b4983 in kern_openat (td=0xfffffe00c8149300, fd=<optimized out>, path=<optimized out>, pathseg=<optimized out>, flags=1, mode=<optimized out>) at /usr/src/sys/kern/vfs_syscalls.c:1143 #26 0xffffffff8068ea5c in syscallenter (td=0xfffffe00c8149300) at /usr/src/sys/amd64/amd64/../../kern/subr_syscall.c:189 (kgdb) frame 16 #16 0xffffffff8034d5b0 in g_slice_access (pp=0xfffff80003ca5100, dr=1, dw=0, de=0) at /usr/src/sys/geom/geom_slice.c:127 127 if ((pp->acw + dw) > 0 && pp2->ace > 0) (kgdb) p pp2 $2 = (struct g_provider *) 0x0 pp2 is null, and pp2->ace crashes the system. Does the above crash pattern rings any bell? My system uses UFS SU+trim on GELI. On reboot, I had to manually run fsck. At the end I did reinstall successfully world from my poudriere server through NFS, since I wasn't sure about the state of the files in /usr/obj... Regards, Ali
