I have attached the oops message and also the ksymoops output. I get the same behaviour with the 08int patch applied also. The OOPs message attached was obtained on a 2.6.0-test1-mm2-08int. Basically, the system just freezes while performing random tasks. Sometimes it happes just after loading xmms and starting to play a song. Sometimes I can do that and open my browser and surf a bit before it freezes. However, every session ends in a freeze. AFAICS, there is no discernible pattern of usage that leads to a freeze. It may occur while processing the startup scripts or while starting X or at any moment during an X session. Once the system is frozen, I can still move the mouse or switch to a virtual console. But I cannot run any programs. If the freeze occurs in X, I do not see the oops message. So the oops message I have attached happened just after I typed `startx` at the console after a fresh reboot. - Apurva --bg08WKrSYDhXBjb5 Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="oops.txt" Unable to handle kernel NULL pointer dereference at virtual address 00000014 print eip: *pde=00000000 Oops: 0000 [#1] PREEMPT CPU : 0 EIP : 0060 " [] Not tainted VLI EFLAGS : 00010202 EIP is at journal_dirty_metadata+0x38/0x210 eax : c7aac000 ebx : 00000000 ecx : 00000000 edx : cb4c0e20 esi : cadfd180 edi : cbd37bc0 ebp : cb070220 esp : c7aade78 ds : 007b es : 007b ss : 0068 Process X (pid: 1322, threadinfo = c7aac000 task = c7b34d60 ) Stack: cbd4c660 c7abd148 c0152c6b c015127f cb4c0e20 cb4c0e20 cb070220 00000001 c7abd148 c01896c7 cb070220 cb4c0e20 00001000 c7aadebc 00000001 00000001 00000000 00000030 00000001 00000001 000006c6 00075081 cbd4a3a0 00004000 Call Trace: [] __getblk+0x2b/0x60 [] wake_up_buffer+0xf/0x30 [] ext3_getblk+0x107/0x2a0 [] ext3_bread+0x33/0xc0 [] ext3_mkdir+0x107/0x2e0 [] ext3_mkdir+0x0/0x2e0 [] vfs_mkdir+0x6a/0xc0 [] sys_mkdir+0xc6/0x100 [] sys_newuname+0x86/0x90 [] sysenter_past_esp+0x52/0x71 Code: 24 2c 8b 75 00 8b 5a 24 f6 45 18 04 8b 3e 0f 84 df 01 00 00 b8 01 00 00 00 85 c0 0f 85 d1 00 00 00 b8 00 e0 ff ff 21 e0 ff 40 14 <8b> 43 14 3b 45 00 0f 84 6c 01 00 b8 00 e0 ff ff 21 e0 ff 40 <6>note: x[1322] exited with preempt_count 1 giving up --bg08WKrSYDhXBjb5 Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="ksymoops.output" ksymoops 2.4.9 on i686 2.6.0-test1-mm2.
