I made some powernow experiments on a dual core amd64 box, running the 64-bit debug on-20060828 kernel. At some point the kernel seemed to make no more progress (probably a bug in the multiprocessor powernow code), the gui was stuck, so I typed (blind) F1-A + $<systemdump. Writing the crashdump worked.
When the system rebooted, mounting the zfs filesystems paniced the box with the following failed assertion; rebooting the debug kernel (both 64-bit and 32-bit) resulted in the same assertion failed panic: > ::status debugging crash dump vmcore.12 (32-bit) from moritz operating system: 5.11 wos_b48_2_debug (i86pc) panic message: assertion failed: zp_error != 0 && dzp_error != 0, file: ../../common/fs/zfs/zfs_acl.c, line: 1537 dump content: kernel pages only > ::stack vpanic(fea6bfa4, f85a5984, f85a5964, 601) assfail+0x5a(f85a5984, f85a5964, 601) zfs_zaccess_delete+0x13a(ca45a790, ca45a670, cd1f1e78) zfs_remove+0x88(ca453340, caa5b028, cd1f1e78) fop_remove+0x1e(ca453340, caa5b028, cd1f1e78) zfs_replay_remove+0x57(c94172c0, caa5b000, 0) zil_replay_log_record+0x256(c9da24c0, ca9e2708, ca6ded54, 70cf, 0) zil_parse+0x374(c9da24c0, 0, f8568188, ca6ded54, 70cf, 0) zil_replay+0xba(ca454f88, c94172c0, c94172e4, c50b2c6c, f8572ba0) zfs_domount+0x24a(c58cbf00, c79e89c0, cd1f1588) zfs_mount+0x109(c58cbf00, ca6e4c00, ca6def84, cd1f1588) fsop_mount+0x1a(c58cbf00, ca6e4c00, ca6def84, cd1f1588) domount+0x8ad(0, ca6def84, ca6e4c00, cd1f1588, ca6def48) mount+0x6f(ca6def84, ca6def68) syscall_ap+0x4d() sys_sysenter+0x1a2() Now I see that exactly the same panic with identical stack backtrace has already filed as bug 6466374, http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6466374 But why is bug 6466374 closed as a duplicate of bug 6413510? I'd say that bugs 6466374 and 6413510 are about completely different issues... When looking at the code in zfs_zaccess_delete() and zfs_zaccess_common(), it seems that when replaying a "remove" from the log, a debug version of the zfs filesystem module always panics with the "zp_error != 0 && dzp_error != 0" failed assertion.
