[-- Attachment #1 --] Hi, I do have a crash on a NFS client with stable of today (4c4633fdffbe8e4b6d328c2bc9bb3edacc9ab50a). It is also autofs related. Maybe it is the same problem. I have ports automounted on /am/ports. When I do cd /am/ports/sys and type tab to autocomplete it crashes with the below stack trace. If I plainly mount ports on /usr/ports and do the same everything works. I am using NFSv3 Peter Fatal trap 12: page fault while in kernel mode cpuid = 2; apic id = 04 fault virtual address = 0x89 fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff809645d4 stack pointer = 0x28:0xfffffe00acadb830 frame pointer = 0x28:0xfffffe00acadb830 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 = 6869 (csh) trap number = 12 panic: page fault cpuid = 2 time = 1705306940 KDB: stack backtrace: #0 0xffffffff806232f5 at kdb_backtrace+0x65 #1 0xffffffff805d7a02 at vpanic+0x152 #2 0xffffffff805d78a3 at panic+0x43 #3 0xffffffff809d58ad at trap_fatal+0x38d #4 0xffffffff809d58ff at trap_pfault+0x4f #5 0xffffffff809af048 at calltrap+0x8 #6 0xffffffff804c7a7e at ncl_bioread+0xb7e #7 0xffffffff804b9d90 at nfs_readdir+0x1f0 #8 0xffffffff8069c61a at vop_sigdefer+0x2a #9 0xffffffff809f8ae0 at VOP_READDIR_APV+0x20 #10 0xffffffff81ce75de at autofs_readdir+0x2ce #11 0xffffffff809f8ae0 at VOP_READDIR_APV+0x20 #12 0xffffffff806c3002 at kern_getdirentries+0x222 #13 0xffffffff806c33a9 at sys_getdirentries+0x29 #14 0xffffffff809d6180 at amd64_syscall+0x110 #15 0xffffffff809af95b at fast_syscall_common+0xf8 > On 15 Jan 2024, at 06:46, FreeBSD User <freebsd@walstatt-de.de> wrote: > > Am Sun, 14 Jan 2024 20:34:12 -0800 > Cy Schubert <Cy.Schubert@cschubert.com <mailto:Cy.Schubert@cschubert.com>> schrieb: > >> In message <CAM5tNy5aat8vUn2fsX9jV=D9yGZdnO20Q0Ea7qtszx+zSES2bw@mail.gmail.c >> om> >> , Rick Macklem writes: >>> On Sat, Jan 13, 2024 at 12:39=E2=80=AFPM Ronald Klop <ronald-lists@klop.ws>= >>> wrote: >>>> >>>> >>>> Van: FreeBSD User <freebsd@walstatt-de.de> >>>> Datum: 13 januari 2024 19:34 >>>> Aan: FreeBSD CURRENT <freebsd-current@freebsd.org> >>>> Onderwerp: NFSv4 crash of CURRENT >>>> >>>> Hello, >>>> >>>> running CURRENT client (FreeBSD 15.0-CURRENT #4 main-n267556-69748e62e82a= >>> : Sat Jan 13 18:08:32 >>>> CET 2024 amd64).
