* Author: arc...@b1t.name * Status: New * Priority: Low * Assignee: * Category: VFS subsystem * Target version: ---------------------------------------- One fine day I was doing many things simultaneously when: panic: assertion "pbase != 0 && ((lbase + lsize - 1) & pmask) == pbase" failed in hammer2_io_getblk at /usr/src/sys/vfs/hammer2/hammer2_io.c:95 Trace beginning at frame 0xffffffe0cfa077b0 panic() at panic+0x25f 0xffffffff8027bb8e panic() at panic+0x25f 0xffffffff8027bb8e hammer2_io_getblk() at hammer2_io_getblk+0x9f 0xffffffff81f57e78 _hammer2_io_new() at _hammer2_io_new+0x47 0xffffffff81f586ea hammer2_io_newnz() at hammer2_io_newnz+0xf 0xffffffff81f58f18 hammer2_strategy_xop_write() at hammer2_strategy_xop_write+0x823 0xffffffff81f49c21 When system rebooted it just failed again with the same trace during `savecore`.
