From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: We have an ASUS CUR-DLS system, 4gb RAM, 2 x PIII (1ghz), dual SCSI disks, IDE CDROM. The firmware is the latest version. I'm not booting with any special options. Should I try to lower the size of RAM seen by the kernel? We're only running Apache, Mod_perl, WebRT and MySQL on this box. It's purely being used for trouble ticket tracking. It's not even being used that hard. The system has been giving us problems in SMP kernels for all FC3 kernels I have tried. Finally got a crash dump in /var/log/messages for the 2.6.10-1.766 kernel: Feb 23 19:25:12 rt3 kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000000 Feb 23 19:25:12 rt3 kernel: printing eip: Feb 23 19:25:12 rt3 kernel: c0116a5e Feb 23 19:25:12 rt3 kernel: *pde = 3730a001 Feb 23 19:25:12 rt3 kernel: Oops: 0000 [#1] Feb 23 19:25:12 rt3 kernel: SMP Feb 23 19:25:12 rt3 kernel: Modules linked in: parport_pc lp parport autofs4 nfs lockd sunrpc md5 ipv6 ohci_hcd i2c_piix4 i2c_core e100 mii floppy dm_snapshot d m_zero dm_mirror ext3 jbd dm_mod sym53c8xx scsi_transport_spi sd_mod scsi_mod Feb 23 19:25:12 rt3 kernel: CPU: 0 Feb 23 19:25:12 rt3 kernel: EIP: 0060:[<c0116a5e>] Not tainted VLI Feb 23 19:25:12 rt3 kernel: EFLAGS: 00010246 (2.6.10-1.766_FC3smp) Feb 23 19:25:12 rt3 kernel: EIP is at pgd_free+0x6/0x30 Feb 23 19:25:12 rt3 kernel: eax: 00000000 ebx: 00000000 ecx: c2f56200 edx: c2f57060 Feb 23 19:25:12 rt3 kernel: esi: 00000000 edi: 00000000 ebp: f6f02e68 esp: f6f02e48 Feb 23 19:25:12 rt3 kernel: ds: 007b es: 007b ss: 0068 Feb 23 19:25:12 rt3 kernel: Process httpd (pid: 3287, threadinfo=f6f02000 task=c 336b040) Feb 23 19:25:12 rt3 kernel: Stack: f0c2ebc2 c0308ba0 c011bfe1 f0c2ebc2 c011926b c2f57060 9a8aef00 f0c2ebc2 Feb 23 19:25:12 rt3 kernel: f6f02ec4 c02bb362 c03ebe0c f6f02ecc f7dc7060 c03ebe08 00000000 f7dc7060 Feb 23 19:25:12 rt3 kernel: 00000000 c2f579c0 c2f57060 00000000 0001b207 5ef02500 000f4c9e c0308ba0 Feb 23 19:25:12 rt3 kernel: Call Trace: Feb 23 19:25:12 rt3 kernel: [<c011bfe1>] __mmdrop+0x1a/0x2e Feb 23 19:25:12 rt3 kernel: [<c011926b>] finish_task_switch+0x46/0x66 Feb 23 19:25:12 rt3 kernel: [<c02bb362>] schedule+0x8ca/0x90d Feb 23 19:25:12 rt3 kernel: [<c02bb846>] schedule_timeout+0xce/0xe9 Feb 23 19:25:12 rt3 kernel: [<c01256af>] process_timeout+0x0/0x5 Feb 23 19:25:12 rt3 kernel: [<c0161d42>] do_select+0x277/0x2ac Feb 23 19:25:12 rt3 kernel: [<c012e87a>] remove_wait_queue+0xf/0x34 Feb 23 19:25:12 rt3 kernel: [<c0161991>] __pollwait+0x0/0x95 Feb 23 19:25:12 rt3 kernel: [<c0162097>] sys_select+0x30d/0x49e Feb 23 19:25:12 rt3 kernel: [<c01215b0>] sys_waitpid+0x13/0x17 Feb 23 19:25:12 rt3 kernel: [<c0103c97>] syscall_call+0x7/0xb Feb 23 19:25:12 rt3 kernel: Code: f4 3e c0 81 ea 01 00 00 40 e8 e5 90 02 00 eb e 7 a1 50 f4 3e c0 89 ea e8 d7 90 02 00 31 c0 5f 5d 5b 5e 5f 5d c3 56 89 c6 53 31 db <8b> 14 de 43 a1 54 f4 3e c0 81 ea 01 00 00 40 e8 b4 90 02 00 83 Version-Release number of selected component (if applicable): kernel-2.6.10-1.766_FC3 How reproducible: Always Steps to Reproduce: 1. Install system 2. Boot into SMP kernel 3. Wait until it hangs. Actual Results: System hangs. Needs a reset or power cycle to get it to reboot. Expected Results: System should just run. Additional info:
I have a similar issue with kernel-2.6.10- 1.766_FC2... when running this kernel, I've had to reboot every few days. Today I was installing a pretty large app and it would hang every time I attempted the install. Complete lockout: not possible to do anything even from the physical console. After rebooting and selecting an earlier version of the SMP kernel, it was possible to install the app without another system hang.
http://people.redhat.com/davej/kernels/Fedora/ The 2.6.11 based test kernels here will probably help your problem. Please test it and report back.
No response for months, assuming solved.
