Hello, just tried the current hg with some kernels and with all I got the same problem vdr quits and is marked as defunct which I can't remove, which leaves me the only choice of rebooting :( ksymoops 2.4.9 on x86_64 2.6.16-rc2. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.6.16-rc2/ (default) -m /usr/src/linux/System.map (default) Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options. Error (regular_file): read_ksyms stat /proc/ksyms failed No modules in ksyms, skipping objects No ksyms, skipping lsmod Unable to handle kernel NULL pointer dereference at 0000000000000010 RIP: <ffffffff803bea11>{__mutex_lock_interruptible_slowpath+65} Oops: 0000 [1] CPU 0 Pid: 13919, comm: vdr Tainted: P 2.6.16-rc2 #1 RIP: 0010:[<ffffffff803bea11>] <ffffffff803bea11>{__mutex_lock_interruptible_slowpath+65} Using defaults from ksymoops -t elf64-x86-64 -a i386:x86-64 RSP: 0018:ffff81003ad79cf0 EFLAGS: 00010007 RAX: 000000003ad79d47 RBX: 0000000000000008 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 0000000000000003 RDI: ffff810034633dd0 RBP: ffff81003ad79d28 R08: 0000000000000000 R09: ffff81002cf43ed8 R10: 0000000000466440 R11: 0000000000000206 R12: ffff81003b88c968 R13: ffff81003b88c968 R14: 0000000000000001 R15: 0000000000000000 FS: 00002b37319d1350(0000) GS:ffffffff804f6000(0000) knlGS:00000000f73786b0 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 0000000000000010 CR3: 000000003a87f000 CR4: 00000000000006e0 Stack: ffffffff80124cce 0000000300000000 ffff81003b88c960 ffff81003ad79e48 00007fffffb76c48 ffffffff8850a8f0 ffff81003dda91c0 ffff8100ffffffff ffffffff80124d17 ffffc2000063de58 Call Trace: <ffffffff80124cce>{__wake_up_common+62} <ffffffff8850a8f0>{:dvb_ttpci:dvb_ca_ioctl+0} <ffffffff80124d17>{__wake_up+23} <ffffffff803bedc8>{__up_wakeup+53} <ffffffff8850b353>{:dvb_ttpci:.text.lock.av7110_ca+15} <ffffffff803bea78>{.text.lock.mutex+15} <ffffffff884afdf5>{:dvb_core:dvb_demux_do_ioctl+885} <ffffffff8850a8f0>{:dvb_ttpci:dvb_ca_ioctl+0} <ffffffff884ae636>{:dvb_core:dvb_usercopy+214} <ffffffff801634d4>{__dentry_open+260} <ffffffff801635d2>{nameidata_to_filp+34} <ffffffff8016361a>{do_filp_open+42} <ffffffff801758de>{do_ioctl+78} <ffffffff80175b5d>{vfs_ioctl+621} <ffffffff80175bcd>{sys_ioctl+77} <ffffffff8010a9a6>{system_call+126} Code: 48 8b 43 08 8b 40 10 a8 04 74 17 48 8b 04 24 48 8b 54 24 08 >>RIP; ffffffff803bea11 <__mutex_lock_interruptible_slowpath+41/99> <===== >>RAX; 000000003ad79d47 <phys_startup_64+3ac79c47/ffffffff7fffff00> >>RDI; ffff810034633dd0 <phys_startup_64+ffff810034533cd0/ffffffff7fffff00> >>RBP; ffff81003ad79d28 <phys_startup_64+ffff81003ac79c28/ffffffff7fffff00> >>R09; ffff81002cf43ed8 <phys_startup_64+ffff81002ce43dd8/ffffffff7fffff00> >>R10; 0000000000466440 <phys_startup_64+366340/ffffffff7fffff00> >>R12; ffff81003b88c968 <phys_startup_64+ffff81003b78c868/ffffffff7fffff00> >>R13; ffff81003b88c968 <phys_startup_64+ffff81003b78c868/ffffffff7fffff00> Trace; ffffffff80124cce <__wake_up_common+3e/70> Trace; ffffffff8850a8f0 <_end+7fe38f0/7f0d9000> Trace; ffffffff803bedc8 <__up_wakeup+35/67> Trace; ffffffff803bea78 <.text.lock.mutex+f/17> Trace; ffffffff8850a8f0 <_end+7fe38f0/7f0d9000> Trace; ffffffff801634d4 <__dentry_open+104/1e0> Trace; ffffffff8016361a <do_filp_open+2a/40> Trace; ffffffff80175b5d <vfs_ioctl+26d/290> Trace; ffffffff8010a9a6 <system_call+7e/83> Code; ffffffff803bea11 <__mutex_lock_interruptible_slowpath+41/99> 0000000000000000 <_RIP>: Code; ffffffff803bea11 <__mutex_lock_interruptible_slowpath+41/99> <===== 0: 48 8b 43 08 mov 0x8(%rbx),%rax <===== Code; ffffffff803bea15 <__mutex_lock_interruptible_slowpath+45/99> 4: 8b 40 10 mov 0x10(%rax),%eax Code; ffffffff803bea18 <__mutex_lock_interruptible_slowpath+48/99> 7: a8 04 test $0x4,%al Code; ffffffff803bea1a <__mutex_lock_interruptible_slowpath+4a/99> 9: 74 17 je 22 <_RIP+0x22> Code; ffffffff803bea1c <__mutex_lock_interruptible_slowpath+4c/99> b: 48 8b 04 24 mov (%rsp),%rax Code; ffffffff803bea20 <__mutex_lock_interruptible_slowpath+50/99> f: 48 8b 54 24 08 mov 0x8(%rsp),%rdx CR2: 0000000000000010 1 warning and 1 error issued.
