Description of problem: When switching from runlevel 5 to any other runlevel the kernel panics. This only occurs when the machine is in runlevel 5. If I bring the machine up in runlevel 3 and then switch to runlevel 6 it reboots normally. Version-Release number of selected component (if applicable): [root@tigger2 ~]# uname -r 2.6.18-1.2849.fc6 xorg-x11-server-Xorg-1.1.1-47.1.fc6 [root@tigger2 log]# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 6 model name : Intel(R) Pentium(R) 4 CPU 3.40GHz stepping : 4 cpu MHz : 3391.589 cache size : 2048 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 fpu : yes fpu_exception : yes cpuid level : 6 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall lm constant_tsc pni monitor ds_cpl est tm2 cid cx16 xtpr lahf_lm bogomips : 6786.42 clflush size : 64 cache_alignment : 128 address sizes : 36 bits physical, 48 bits virtual power management: [root@tigger2 log]# The machine is an HP DC5100 with a fresh install of FC6 and all of the updates applied. How reproducible: every time I try to switch runlevels from RL 5 Steps to Reproduce: 1.boot machine into runlevel 5 2. type init 6 on a command line or press <ctrl><alt><del> 3. Actual results: Kernel panics Expected results: Normal reboot Additional info: On one of the panics I saw the following message: BUG: Spinlock recursion on CPU 0, XORG/2644 (Not Tainted). Ths is a new machine and install of FC6. Please let me know what other information would be useful in debugging this. I do not see anything unusual in the logs.
FYI, I updated the kernel to 2.6.18-1.2860.fc6. No change in behavior
Created attachment 143976 [details] Output from netconsole when kernel panics.
Created attachment 143978 [details] This is the output from a panic while running yum update. This dump was captured while running yum update via netconsole.
Created attachment 143979 [details] Kernel panic after installing all updates. This panic was captured after all updates were installed and the machine was rebooted. The panic was captured via netconsole.
The panics occur when the machine is loaded with the x86_64 version of FC6. I reloaded the machine with the i386 version and the machine operated normally. Also fixed spelling error in the summary.
I too have a similar problem. My system runs a FC6, x86_64. My /proc/cpuinfo is [dhaval@localhost installs]$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz stepping : 6 cpu MHz : 1862.000 cache size : 2048 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall lm constant_tsc pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_lm bogomips : 3728.47 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz stepping : 6 cpu MHz : 1862.000 cache size : 2048 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall lm constant_tsc pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_lm bogomips : 3724.19 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: [dhaval@localhost installs]$ My panic though had some ext3 and vfs functions in the trace. If someone can tell me how to use netconsole, I can get the panic details. It is more than once screenful. To cause this panic, I did the following. 1. Boot into init 3 2. Run startx 3. press ^c in the console where i started startx. BTW, the system hangs when I shutdown. My guess was it is because of the panic.
[dhaval@localhost ~]$ uname -r 2.6.18-1.2798.fc6 [dhaval@localhost ~]$
(This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora!
This problem was resolved during the F7 Beta cycle.
