Hello I am using a Dell Latitude D630 and once I was shutting down my computer when I got a "unable to handle kernel NULL pointer dereference at 00000018" bug followed by some messages which I typed the most below : [sda] Synchronizing SCSI cache [sda] Stopping disk BUG: unable to handle kernel NULL pointer dereference at 00000018 IP: [<c01c316c>] sysfs_remove_one+0x13/0x59 *pde = 00000000 Oops : 0000 [#1] SMP last sysfs file: /sys/devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/removable It tells me that the last unloaded module was fuse Pid: 12981, comm: halt Not tainted (2.6.29-2-686 #1) Latitude D630 EIP : 0060:[<c01c316c>] EFLAGS: 00010246 CPU: 0 EIP is at sysfs_remove_one+0x13/0x59 EAX: 00000000 EBX: 00000018 ECX: f53d3e58 EDX: f6b13b90 ESI: f7022350 EDI: f7022368 EBP: f53d2000 ESP: f53d3e50 DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Process halt (pid: 12981, ti=f53d2000 task=f6af37f0 task.ti=f53d2000) Stack: f732c900 c01c387e f7022350 00000000 f6b0ecf0 0000002f f732c900 c03aee7c f7001c20 c01f9c81 f732c900 c01f9ccc f732c91c c01f9c9d 28121969 c01fa749 ef592800 4321fedc c025b2df ffffffff c0131fb0 c01321e1 c17f9820 c02ee9b8 Call trace : [<c01c387e>] sysfs_remove_dir+0x46/0x66 [<c01f9c81>] kobject_del+0xc/0x28 [<c01f9ccc>] kobject_release+0x2f/0x4f [<c01f9c9d>] kobject_release+0x0/0x4f [<c01fa749>] kref_put+0x39/0x43 [<c025b2df>] device_shutdown+0x54/0x69 [<c0131fb0>] kernel_power_off+0xa/0x2f [<c01321e1>] sys_reboot+0xf6/0x16c [<c0120e8c>] try_to_wake_up+0x14e/0x157 [<c0139b45>] sched_clock_cpu+0x136/0x147 [<c010212e>] __switch_to+0xcd/0x14e [<c011cecb>] pick_next_task_fair+0x80/0x87 [<c012267b>] finish_task_switch+0x22/0xa5 [<c02e61c3>] schedule+0x6dd/0x754 [<c0198841>] mntput_no_expire+0x1a/0xfe [<c0185c71>] filp_close+0x4e/0x54 [<c0185cdb>] sys_close+0x64/0x9f [<c010341b>] sysenter_do_call+0x12/0x2f Code: e8 b0 26 12 00 58 5a c3 90 90 90 8b 40 20 0f 94 c0 0f b6 c0 c3 f6 42 1d 02 89 c1 53 74 04 0f 0b eb fe 8b 42 08 8d 58 18 <8b> 40 18 eb 18 39 d0 75 0e 8b 42 0c 00 00 00 00 EIP: [<c01c316c>] sysfs_remove_one+0x13/0x59 SS:ESP 0068:f53d3e50 /etc/rc0.d/S90halt: line 19: 12981 Segmentation fault halt -d -f $netdown $poweroff $hddown sda is my hard disk and I have kernel modesetting enabled. I don't know how to reproduce this bug again, I think that is because I made some suspend to disk, suspend to RAM and resuming before. It is new that I have linux-image-2.6.29-2-686 installed and kernel modesetting enabled. So I will see later if this bug comes with suspending. I found almost the same bug once I was resuming from suspend to disk and removed a USB Stick during the same time (I can't reproduce this one either) and I notice that with this one it was said : BUG: unable to handle kernel NULL pointer dereference at 0000001c and it has a different call trace. additional informations : coreutils/testing uptodate 7.3-1 initscripts/stable uptodate 2.86.ds1-61 xserver-xorg-video-intel/sid uptodate 2:2.7.1-1 Bye Jonas --- System information. --- Architecture: i386 Kernel: Linux 2.6.29-2-686 Debian Release: squeeze/sid 450 testing ftp.de.debian.org 400 stable ftp.de.debian.org 300 unstable ftp.de.debian.org 200 experimental ftp.ch.debian.org --- Package information. --- Depends (Version) | Installed =====================================-+-============= module-init-tools | 3.7-pre9-1 initramfs-tools (>= 0.55) | 0.93.2 OR yaird (>= 0.0.13) | OR linux-initramfs-tool | Recommends (Version) | Installed =========================-+-=========== libc6-i686 | 2.9-4 Suggests (Version) | Installed ===============================-+-=========== linux-doc-2.6.29 | grub | OR lilo | --- Output from package bug script --- -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
