--Apple-Mail=_74D47009-3EDF-46D9-851C-F1EF5B50FAC6 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=us-ascii Hello, I have been running a generic 9.1 kernel for some time, and tried to = upgrade to 9.2. The upgrade itself goes smoothly, but after running a = few minutes I get a panic like this: panic: vm_fault: fault on nofault entry, addr: ffffff836e0fc000 cpuid =3D 0 KDB: stack backtrace: n0 0xffffffff80947986 at kdb_backtrace+0x66 n1 0xffffffff8090d9ae at panic+0x1ce nz 0xffffffff80b79eca at vm_fault_hold+0x1f8a n3 0xffffffff80b7a663 at vm_fault+0x73 n4 0xffffffff80cf260f at trap_pfault+0x3~f ns 0xffffffff80cf29e4 at trap+0x344 n6 0xffffffff80cdbd13 at calltrap+0x8 n? 0xffffffff80d96898 at VOP_ADD_WRITECOUNT_APV+0x78 na 0xffffffff809bad48 at vn_open_cred+0x5d8 n9 0xffffffff809b676a at kern_openat+0x20a n10 0xffffffff80cf187a at amd64_syscall+0x5ea n11 0xffffffff80cdbff7 at Xfast_syscall+0xf7 Uptime: 5m24s This is a production system for which I don't have a similar setup to = test changes on, so I rolled back (via a zfs snapshot) to 9.1 after the = panic consistently happened after rebooting. I can't say with certainty = what was causing the crash: after booting I performed my usual system = tasks which involved mounting some pefs filesystems (and thus loading = the pefs kernel module) and starting up a Postgres server. After rolling back to 9.1 I did repeat the upgrade process and ended up = with the same panic, so I have since left it in 9.1. I'm afraid I'm relatively new to FreeBSD, so I don't have any crash = dumps. I wondered if anyone had any ideas on what might be causing this = type of panic?
