From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux ppc; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.7.7-2 Description of problem: This bug is similar to #129405 and #146190. When I close the lid on my iBook G4, wait for the white LED to start pulsating slowly, then re-open the lid, both my USB mouse and my USB keyboard cease to work. Only a reboot restores USB. Version-Release number of selected component (if applicable): kernel-2.6.11-1.1275_FC4 How reproducible: Always Steps to Reproduce: 1. Boot. 2. Close the lid. 3. Open the lid. 4. Try to use either a USB mouse or a USB keyboard. Actual Results: Neither the USB keyboard nor the USB mouse works. Expected Results: Complete USB recovery and continued normal USB operation. Additional info:
Created attachment 113890 [details] suspend/resume-related output from dmesg, including a call from an invalid context, and some "badness".
Not PPC-specific -- this is general USB brokenness. Paulus sent patches to David Brownell a _long_ time ago but they're still not merged. Workaround for now is to unload ehci_hcd; the OHCI (USB1) driver tends to work. I'll chase them up and see about putting them in the RPM. The 'Badness in wait_for_ready at drivers/ide/ide-iops.c:520' is just whinging about an mdelay -- it's also harmless. Again, it isn't PPC-specific except to the extent that PPC users seem to be the only people for whom suspend is reliable enough to actually get used :)
ok, thanks. For info, theres an IDE update on the way from Alan, (its already in CVS, but is currently borken -- more fixes tomorrow). That may fix the badness in ide.
The EHCI thing should be fixed in a 1.1280 or later kernel. Since the S390 machines appear to be AWOL from the build farm at the moment that may not turn up very soon -- in the meantime please test http://david.woodhou.se/kernel-2.6.11-1.1279_FC4.dwmw2.ppc.rpm http://david.woodhou.se/kernel-devel-2.6.11-1.1279_FC4.dwmw2.ppc.rpm
Actually don't bother testing that -- the IDE changes prevent it from booting.
A 1282 kernel will appear at http://people.redhat.com/davej/kernels/Fedora/FC4 in a while, that *should* hopefully fix the broken IDE problem.
It boots, I have USB mouse after suspend. kallsyms is broken though... note four functions without names: Debug: sleeping function called from invalid context at include/asm/semaphore.h:71 in_atomic():0, irqs_disabled():1 Call trace: [c0019714] __might_sleep+0xd4/0x100 [c00109d4] pmac_low_i2c_open+0x64/0xa0 [c03fba0c] 0xc03fba0c [c03fbf70] 0xc03fbf70 [c03f44a8] 0xc03f44a8 [c04072f4] 0xc04072f4 [c00b2344] do_ioctl+0x84/0x90 [c00b23dc] vfs_ioctl+0x8c/0x460 [c00b2844] sys_ioctl+0x94/0xb0 [c00048a0] ret_from_syscall+0x0/0x44
