Hi all. I am running the 2.4.18-3smp kernel and over the poast couple of days, ext3 has been crashing. Here is the output: Assertion failure in journal_commit_transaction() at commit.c:535: "buffer_jdirty(bh)" ------------[ cut here ]------------ kernel BUG at commit.c:535! invalid operand: 0000 loop autofs nfs lockd sunrpc 3c59x ns83820 ide-scsi ide-cd cdrom usb-uhci usbc CPU: 0 EIP: 0010:[<f88540e4>] Not tainted EFLAGS: 00010286 EIP is at journal_commit_transaction [jbd] 0xb04 (2.4.18-3smp) eax: 0000001c ebx: 0000000a ecx: c02eee60 edx: 00004010 esi: f1a789a0 edi: e0a6bd80 ebp: f6968000 esp: f6969e78 ds: 0018 es: 0018 ss: 0018 Process kjournald (pid: 223, stackpage=f6969000) Stack: f885aeee 00000217 f61aa01e 00000000 00000f2c cce460d4 00000000 f67909a0 f4fecf70 000003ee f6622240 c1e3ec00 f6683bc0 f6622240 f68812c0 f68816e0 f6881a40 f6881f20 f6881560 f6881f80 f6881860 f0dd8a20 f0dd8ba0 f0dd80c0 Call Trace: [<f885aeee>] .rodata.str1.1 [jbd] 0x26e [<c0120f3b>] do_softirq [kernel] 0x7b [<c010a77f>] do_IRQ [kernel] 0xdf [<c0119048>] schedule [kernel] 0x348 [<f88567d6>] kjournald [jbd] 0x136 [<f8856680>] commit_timeout [jbd] 0x0 [<c0107286>] kernel_thread [kernel] 0x26 [<f88566a0>] kjournald [jbd] 0x0 Code: 0f 0b 5a 59 6a 04 8b 44 24 18 50 56 e8 4b f1 ff ff 8d 47 48 Does anyone have any idea why this would happen and more importantly, how to fix it?
