As the bug ouccured with LVM __and__ with MD it looks like a ext3-problem. Tom Rini reported the same problem on a PPC-Box. Possibly it is a big endian problem. The message was again: kernel: Assertion failure in journal_forget() at transaction.c:1184: "!jh->b_committed_data" Here a have a new backtrace, I resolved the functions manually from system.map -hopefully without a mistake. kernel BUG at transaction.c:1184! illegal operation: 0001 CPU: 1 Process rm (pid: 1917, stackpage=06125000) Kernel PSW: 070c0000 8008023c =journal_forget task: 06124000 ksp: 06125938 pt_regs: 061258a0 Kernel GPRS: 00000000 8001c118 00000022 00000001 8008023a 00c2a000 00197198 00000001 12fc1880 08d06494 00001899 1575c9b0 0001f94c 800800ac 8008023a 06125938 Kernel ACRS: 00000000 00000000 00000000 00000000 00000001 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 Kernel BackChain CallChain 06125938 [<0008023a>] =journal_forget 061259a0 [<000747e6>] =ext3_forget 06125a08 [<00076c00>] =ext3_clear_blocks 06125a70 [<00076d20>] =ext3_free_data 06125ae8 [<00076ee4>] =ext3_free_branches 06125b60 [<00076e44>] =ext3_free_branches 06125bd8 [<00076e44>] =ext3_free_branches 06125c50 [<0007723c>] =ext3_truncate greetings
