Most recent kernel where this bug did *NOT* occur: FC6 2.6.20 kernels / 2.6.21.3 Distribution: Fedora 7 Hardware Environment: Dell Inspiron 8500 Software Environment: Problem Description: I have just done a clean install of fedora 7 on my machine, replacing Fedora Core 6. When I resume my machine from suspend, it panics. My display is not reiinitialised, so using /sys/power/pm_trace I identified that the device is the following; 00:1d.0 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1 (rev 03) With the current fedora kernel (kernel-2.6.21-1.3194.fc7) I see the following backtrace on bootup: Jun 1 09:00:39 echo kernel: ACPI: PCI Interrupt 0000:01:00.0[A] -> Link [LNKA] -> GSI 11 (level, low) -> IRQ 11 Jun 1 09:00:39 echo kernel: BUG: warning at kernel/softirq.c:138/local_bh_enable() (Not tainted) Jun 1 09:00:39 echo kernel: [<c042b0cf>] local_bh_enable+0x45/0x92 Jun 1 09:00:39 echo kernel: [<c06002bd>] cond_resched_softirq+0x2c/0x42 Jun 1 09:00:39 echo kernel: [<c059adf3>] release_sock+0x4f/0x9d Jun 1 09:00:39 echo kernel: [<c05c670d>] tcp_sendmsg+0x90b/0x9f9 Jun 1 09:00:39 echo kernel: [<c05dec95>] inet_sendmsg+0x3b/0x45 Jun 1 09:00:39 echo kernel: [<c0598731>] sock_aio_write+0xf6/0x102 Jun 1 09:00:39 echo kernel: [<c04754ee>] do_sync_write+0xc7/0x10a Jun 1 09:00:39 echo kernel: [<c0436e71>] autoremove_wake_function+0x0/0x35 Jun 1 09:00:39 echo kernel: [<c0475d47>] vfs_write+0xbc/0x154 Jun 1 09:00:39 echo kernel: [<c0476342>] sys_write+0x41/0x67 Jun 1 09:00:39 echo kernel: [<c0404f70>] syscall_call+0x7/0xb Jun 1 09:00:39 echo kernel: [<c0600000>] __sched_text_start+0x6e8/0x89e Jun 1 09:00:39 echo kernel: ======================= I have since pulled Linus' git linux-2.6 tree (version no was 2.6.22-rc3).

Removing the uhci_hcd module allows the machine to resume without panic'ing. Last weekend I was testing the 2.6.21.3 kernel on my fc6 install and this did not panic, although exactly what options I used have been lost due to the f7 install.

Does it oops? Does it call panic()? If so, how do you know this, if your only means of debugging it was pm_trace? I mean, it could be that the machine was hanging during uhci resume rather than oopsing or panicing? Anyway, it might be worth setting up netconsole (Documentation/networking/netconsole.txt) to see if you can get more information out of the machine. Sometimes netconsole doesn't work very well across suspend/resume, because the net device itself gets suspended too. But often it emits useful info. Thanks.

I have at least one test box with uhci_hcd that suspends (to RAM) and resumes successfully. Still, I've tested it with the hibernation and suspend patchset applied only. Simon, can you test 2.6.22-rc3 with the patches from http://www.sisk.pl/kernel/hibernation_and_suspend/2.6.22-rc3/patches/ applied? Greetings, Rafael

Please read "Collecting kernel messages" http://kernelnewbies.org/Linux_Kernel_Tester's_Guide_Chapter3
Testing with a serial console came up blank. I guess the consoles are still suspended at this stage. I've tried using git bisect, but I have ended up with a list of sparc patches. I guess I should try again with a full kernel rebuild at each stage. Shame it takes about 3 hours. I did discover that my port replicator somehow causes my display to re-init on resume and it gets as far as diplaying the yellow "Linu" message.

The patch firewire-implement-suspend-resume-hooks.patch is in 2.6.22-rc4, so I think that this bug can be closed.
Fixed in 2.6.22-rc4, closing. Please reopen if necessary.
