The Oops below happend while swsuspending my Sempron laptop. The system freezes afterwards. On 2.6.12.5 this happened very rarely (but when I had all modules loaded, it happend more often, so I wrote a little script around the swsuspend, removing most modules before the suspend) I noticed that the freezes occur somewhat more often on 2.6.13, 2.6.13.1; but on 2.6.14-rc1 it seems the freeze happens just about always, even with most modules unloaded. .config, System.map and the .jpg of the photo I took of the oops can be found at: http://foko.komputilo.org/~joostje/linux/ Stopping tasks: ------------------------------------------------| Freeing memory... done (25044 pages freed) swsusp: Need to copy 29618 pages Error 12 suspending -----------[ cut here ]-------------- kernel BUG <bad filename>:8680! invalid operand: 0000 [#1] PREEMPT Modules linked in: powernow_k8 processor CPU: 0 EIP: 0060:[<c0130361>] Not tainted VLI EFLAGS: 00010093 (2.6.14-rc1) EIP is at swsusp_suspend+073/0x92 eax: 00007427 ebx: fffffff4 ecx: 00000c00 edx: c04d52a0 esi: 00000004 edi: c03c9d89 ebp: c03f4ec4 esp: c0e13f04 ds: 007b es: 007b ss: 0068 Process sh (pid: 5324, threadinfo=c0e12000 task=c0ccd030) Stack: 00000000 c0130c1f fffffff0 c012f1fd 00000005 c9114004 c012f311 00000004 00000004 cd19d900 cd19d914 c9f0bbc0 c0e13fa4 c017f7ec c03f4ee0 c9114000 00000005 00000005 c017f82c ccea5090 cd19d900 00000005 00000005 c9f0bbc0 Call Trace: [<c0130c1f>] pm_suspend_disk+0x3b/0x7f [<c012f1fd>] enter_state+0x27/0x59 [<c012f311>] state_store+0x7f/0x8b [<c017f7ec>] flush_write_buffer+0x24/0x28 [<c017f82c>] sysfs_write_file+0x3c/0x5b [<c014be06>] vfs_write+0xa1/0x138 [<c014bf3c>] sys_write+0x3b/0x64 [<c0102ca9>] syscall_call+0x7/0xb Code: 00 e8 a4 88 1b 00 85 c0 89 c3 74 0d 50 68 f3 25 3a c0 e8 78 76 fe ff 58 5a e8 7a 88 1b 00 a1 00 b0 45 c0 39 05 08 b0 4b c0 74 02 <0f> 0b e8 21 b4 15 00 fb eb 11 fa 6a 01 e8 9d b1 15 00 89 c3 85 <7> APIC error on CPU0: 80(08) --------------------------- The text above is hand-copied from the photo I took, there may be erros in it, the real photo is here: http://foko.komputilo.org/~joostje/linux/swsuspend-2.6.14-rc1-1.jpg -- Groetjes joostje 47d3fcfe28f2a83497e79d9bc7d5087c-4a1ee1fddab4648175518cb4c1c9edb3ed0e89f0
