A very similar problem was reported before, but I never did figure out what the cause was: http://www.mail-archive.com/[email protected]/msg00250.html I run gentoo myself and haven't seen it firsthand. I've tried remounting between read-only & read-write under a number of different circumstances, but I still can't recreate the problem. What modules do you have loaded? That seemed to make a difference. > At boot I've got this: > > BUG at fs/jfs/jfs_logmgr.c:1622 assert(list_empty(&log->cqueue)) > ------------[ cut here ]------------ > kernel BUG at fs/jfs/jfs_logmgr.c:1622! > invalid operand: 0000 [#1] > PREEMPT SMP > last sysfs file: /class/net/tun1/ifindex > Modules linked in: iptable_nat ip_nat ipt_state ip_conntrack ipt_REJECT > iptable_filter ip_tables parport_pc parport floppy pcspkr rtc ohci1394 > ieee1394 i2c_i801 xfs nvidia tun crc32 rfcomm l2cap bluetooth snd_pcm_oss > snd_mixer_oss snd_emu10k1_synth snd_emux_synth snd_seq_virmidi > snd_seq_midi_event snd_seq_midi_emul snd_seq snd_emu10k1 snd_rawmidi > snd_seq_device snd_ac97_codec snd_pcm snd_timer snd_ac97_bus snd_page_alloc > snd_util_mem snd_hwdep snd soundcore ide_cd i2c_dev w83627hf hwmon_vid > i2c_isa uhci_hcd ehci_hcd usbcore isofs zlib_inflate e1000 > CPU: 0 > EIP: 0060:[<c01eeae6>] Tainted: P VLI > EFLAGS: 00010292 (2.6.15-rc1-mm2) > EIP is at jfs_flush_journal+0x1dc/0x27e > eax: 00000044 ebx: 000000c8 ecx: 00000001 edx: 00000202 > esi: f7d72c34 edi: f7707e7c ebp: f7d72b80 esp: f7707e44 > ds: 007b es: 007b ss: 0068 > Process mount (pid: 2408, threadinfo=f7706000 task=c193e030) > Stack: c0349a6e c0349e97 00000656 c0349e7e f7d72c04 f7d72c18 f880e110 f880e0c8 > 00000002 00000000 c193e030 c0117a34 00000000 00000000 c1906bac 00000000 > f7d12a80 00000000 c193e030 c0117a34 00100100 00200200 00000000 00000000 > Call Trace: > [<c0117a34>] default_wake_function+0x0/0xc > [<c0117a34>] default_wake_function+0x0/0xc > [<c01d746f>] jfs_umount_rw+0x23/0x6c > [<c01d3789>] jfs_remount+0x14f/0x17e > [<c01607a4>] do_remount_sb+0xc1/0x13e > [<c01751de>] do_remount+0x82/0xd5 > [<c0175b50>] do_mount+0x1c0/0x1fc > [<c013ff27>] __alloc_pages+0x45/0x28b > [<c01758af>] exact_copy_from_user+0x26/0x5b > [<c017593a>] copy_mount_options+0x56/0xac > [<c0175ecf>] sys_mount+0x79/0xb5 > [<c0102c3f>] sysenter_past_esp+0x54/0x75 > Code: ff ff e9 95 fe ff ff c7 44 24 0c 7e 9e 34 c0 c7 44 24 08 56 06 00 00 c7 > 44 24 04 97 9e 34 c0 c7 04 24 6e 9a 34 c0 e8 ea de f2 ff <0f> 0b 56 06 97 9e > 34 c0 e9 4f ff ff ff 8d 54 24 24 fc b9 05 00 > Badness in do_exit at kernel/exit.c:795 > [<c011f0f4>] do_exit+0x42f/0x434 > [<c0103f53>] do_divide_error+0x0/0x96 > [<c0104145>] do_invalid_op+0x0/0x99 > [<c01041d5>] do_invalid_op+0x90/0x99 > [<c01eeae6>] jfs_flush_journal+0x1dc/0x27e > [<c011cd96>] release_console_sem+0xb5/0xb7 > [<c011cb95>] vprintk+0x1aa/0x285 > [<c0125347>] try_to_del_timer_sync+0x45/0x4d > [<c0125359>] del_timer_sync+0xa/0x10 > [<c0103837>] error_code+0x4f/0x54 > [<c01eeae6>] jfs_flush_journal+0x1dc/0x27e > [<c0117a34>] default_wake_function+0x0/0xc > [<c0117a34>] default_wake_function+0x0/0xc > [<c01d746f>] jfs_umount_rw+0x23/0x6c This confused me when the problem was first reported. The stack indicates that the partition is being mounted read-only after being mounted read-write. Normally, the root should be mounted read-only (if grub.conf is set up right) and after fsck is called, it should be remounted read-write. It would not normally be mounted back to read-only until the system is shut down. > [<c01d3789>] jfs_remount+0x14f/0x17e > [<c01607a4>] do_remount_sb+0xc1/0x13e > [<c01751de>] do_remount+0x82/0xd5 > [<c0175b50>] do_mount+0x1c0/0x1fc > [<c013ff27>] __alloc_pages+0x45/0x28b > [<c01758af>] exact_copy_from_user+0x26/0x5b > [<c017593a>] copy_mount_options+0x56/0xac > [<c0175ecf>] sys_mount+0x79/0xb5 > [<c0102c3f>] sysenter_past_esp+0x54/0x75 -- David Kleikamp IBM Linux Technology Center ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
