Description of problem: Sometimes the computer just "freezes" when it idles. So i have to turn off the power and then restart it. This started happening after i upgraded to the 2.6.24-kernels. The first line in messages mention nfs4. I'm running a nfs4-server on the machine. But 10.0.0.6 that is mentioned in the log doesn't have nfs4 shares. It only had mounts a nfs4-share from the computer with the problem. I also see that it must be related to wireless.

This panic has happened a couple of more times now. And every time my other computer has mounted a nfs4-share from the computer which panics. So there seems to be a problem with wireless, in connection with nfs4. And it still happens with a newer kernel from koji; kernel-2.6.24.3-28.fc8 From /var/log/messages on the last panic: Mar 12 18:52:57 itse68482 kernel: nfs4_cb: server 10.0.0.6 not responding, timed out Mar 12 18:56:13 itse68482 kernel: BUG: sleeping function called from invalid context at mm/rmap.c:62 Mar 12 18:56:13 itse68482 kernel: in_atomic():0, irqs_disabled():1 Mar 12 18:56:13 itse68482 kernel: Pid: 22128, comm: basename Not tainted 2.6.24.3-28.fc8 #1 Mar 12 18:56:13 itse68482 kernel: [<c047ba33>] anon_vma_prepare+0x1b/0xb5 Mar 12 18:56:13 itse68482 kernel: [<c04782ac>] expand_stack+0x15/0x8c Mar 12 18:56:13 itse68482 kernel: [<c0478dc4>] vma_link+0xa5/0xc3 Mar 12 18:56:13 itse68482 kernel: [<c062d8a5>] do_page_fault+0x22a/0x614 Mar 12 18:56:13 itse68482 kernel: [<c04794a7>] mmap_region+0x30c/0x3c8 Mar 12 18:56:13 itse68482 kernel: [<c062d67b>] do_page_fault+0x0/0x614 Mar 12 18:56:13 itse68482 kernel: [<c062c33a>] error_code+0x72/0x78 Mar 12 18:56:13 itse68482 kernel: [<c04b08ba>] load_elf_binary+0xa4a/0x1573 Mar 12 18:56:13 itse68482 kernel: [<c0485f9c>] __kmalloc+0x93/0xd8 Mar 12 18:56:13 itse68482 kernel: [<c04b08ba>] load_elf_binary+0xa4a/0x1573 Mar 12 18:56:13 itse68482 kernel: [<c0476ccd>] get_user_pages+0x2cc/0x341 Mar 12 18:56:13 itse68482 kernel: [<c048c3ca>] copy_strings+0x169/0x173 Mar 12 18:56:13 itse68482 kernel: [<c048c48c>] search_binary_handler+0x91/0x1d4 Mar 12 18:56:13 itse68482 kernel: [<c048d6b1>] do_execve+0x137/0x1a3 Mar 12 18:56:13 itse68482 kernel: [<c04031ac>] sys_execve+0x2f/0x4f Mar 12 18:56:13 itse68482 kernel: [<c04051da>] syscall_call+0x7/0xb Mar 12 18:56:13 itse68482 kernel: ======================= Mar 12 18:56:13 itse68482 NetworkManager: <WARN> killswitch_getpower_reply(): Error getting killswitch power: No back-end for your operating system.
We took a page fault during load_elf_binary() and called a sleeping function from the interrupt handler.
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
