Distribution: Whitebox linux 3.0 Hardware Environment:IBM xseries 330, dual cpu Pentium III, 2 GB memory, qla2300 FC-HBA. Software Environment: Very much a plain whitebox 3.0, plus the 2.6-kernel and xfs-bits. Working as NFS-server for the home-directories of about 50 active clients, mostly linux but also solaris. Problem Description: I got this oops on my NFS-server. I've had lots of problems with the 2.6 kernel this summer, but after going back to 8K stacks it's been stable for about a month. Unfortunately it crashed again today :( Unable to handle kernel paging request at virtual address ffffff83 printing eip: c013e1e2 *pde = 00003067 *pte = 00000000 Oops: 0002 [#1] SMP Modules linked in: ipv6 lp ipt_REJECT ipt_state ip_conntrack iptable_filter ip_tables ohci_hcd dm_mod CPU: 1 EIP: 0060:[<c013e1e2>] Not tainted EFLAGS: 00010016 (2.6.8.1) EIP is at free_block+0x52/0xe0 eax: ffffff7f ebx: cea6b000 ecx: cea6b8c0 edx: f0c90000 esi: f7fff2e0 edi: 00000000 ebp: f7fff2f8 esp: c2135ed8 ds: 007b es: 007b ss: 0068 Process swapper (pid: 0, threadinfo=c2134000 task=c2131110) Stack: f7fff308 0000000b c214c010 c214c010 c214c000 0000000b f7fff2e0 c013ea30 f7fff2e0 f7fff360 c20225a0 c2135f34 c013eb84 c2134000 c2135f30 c20236a0 00000001 c20225a0 c2135f34 c013ec89 c013ec60 c20236a0 c0124e34 c2135f34 Call Trace: [<c013ea30>] drain_array+0x70/0xa0 [<c013eb84>] cache_reap+0x84/0x160 [<c013ec89>] reap_timer_fnc+0x29/0x50 [<c013ec60>] reap_timer_fnc+0x0/0x50 [<c0124e34>] run_timer_softirq+0xc4/0x160 [<c0120e35>] __do_softirq+0xb5/0xc0 [<c0120e6d>] do_softirq+0x2d/0x30 [<c01131dc>] smp_apic_timer_interrupt+0xcc/0x130 [<c0103d30>] default_idle+0x0/0x40 [<c010676e>] apic_timer_interrupt+0x1a/0x20 [<c0103d30>] default_idle+0x0/0x40 [<c0103d5d>] default_idle+0x2d/0x40 [<c0103df6>] cpu_idle+0x46/0x50 [<c011d3b6>] __call_console_drivers+0x56/0x60 [<c011d4c0>] call_console_drivers+0x90/0x120 [<c025ff67>] vscnprintf+0x17/0x30 Code: 89 50 04 89 02 8b 43 0c c7 03 00 01 10 00 31 d2 c7 43 04 00 <0>Kernel panic: Fatal exception in interrupt In interrupt handler - not syncing Steps to reproduce: Don't know..
Might this be related to this patch ? http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&th=4af201717088ea8e&seekm=2JV7H-6J1-25%40gated-at.bofh.it&frame=off
Is this issue still present with recent kernels?
2.5 years later it's hard to remember how I resolved/worked around this problem.. Most likely it got fixed by a kernel upgrade. Seem to remember I was chasing the bleeding edge for a while until this server got stable. So, please close tgis bug.
