From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.0.3-1.3.1 Firefox/1.0.3 Description of problem: After using an USB device (i tried an usb pen drive, and a digital camera), kernel-2.6.11-1.14_FC3 hangs while logging out from GNOME session. If I don't unplug it, only unmount, I can log out normally. Version-Release number of selected component (if applicable): kernel-2.6.11-1.14_FC3 How reproducible: Always Steps to Reproduce: 1. Plug an USB device. 2. Unmount and unplug it. 3. Log out from GNOME session. 4. The system hangs Actual Results: System hangs. Expected Results: System log out normally. Additional info: I am using a COMPAL CL56 notebook.
I can confirm this. The same happens with the machines of my colleagues.
seems to be fixed in a new kernel: See here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=155472
Since upgrading to 2.6.11-1.14_FC3 the machine seems to lockup after playing wolfenstein (DRI). I've seen this twice now. Not immediately after playing the game, first there's a lot of paging when windows reappear on the desktop. Then after all seems to be there, at some point the machine may hang, for example on closing a window. Not sure if it's related to the USB problem, though I should mention a USB card reader is connected, and a digital camera may have been connected. I'll give kernel-2.6.11-1.19_FC3.i686.rpm a try, and see if the problem doesn't show up again.
It seems that 2.6.11-1.19 is more stable, however when connecting two different card readers at the same time, lsusb got confused and so did the kernel: May 7 16:58:22 home01 kernel: Unable to handle kernel paging request at virtual address 02c00153 May 7 16:58:22 home01 kernel: printing eip: May 7 16:58:22 home01 kernel: dfc87561 May 7 16:58:22 home01 kernel: *pde = 00000000 May 7 16:58:22 home01 kernel: Oops: 0000 [#1] May 7 16:58:22 home01 kernel: Modules linked in: loop nls_utf8 vfat fat snd_pcm_oss snd_mixer_oss usb_storage i915 drm tun parport_pc lp parport autofs4 eeprom lm85 i2c_sensor i2c_isa sunrpc md5 ipv6 ipt_MASQUERADE iptable_nat ipt_LOG ipt_multiport ipt_state ip_conntrack ipt able_filter ip_tables microcode dm_mod video button battery ac uhci_hcd ehci_hcd hw_random i2c_i801 i2c_core snd_intel8x0 snd_ac97_codec s nd_pcm snd_timer snd soundcore snd_page_alloc hisax crc_ccitt isdn slhc tulip e100 mii floppy ext3 jbd ata_piix libata sd_mod scsi_mod May 7 16:58:22 home01 kernel: CPU: 0 May 7 16:58:22 home01 kernel: EIP: 0060:[<dfc87561>] Not tainted VLI May 7 16:58:22 home01 kernel: EFLAGS: 00010246 (2.6.11-1.19_FC3) May 7 16:58:22 home01 kernel: EIP is at bus_reset+0xdc/0x214 [usb_storage] May 7 16:58:22 home01 kernel: eax: 00000015 ebx: dd1ea400 ecx: 02c00007 edx: 0000006b May 7 16:58:22 home01 kernel: esi: ded8e800 edi: fffffff0 ebp: 00000000 esp: ca606e9c May 7 16:58:22 home01 kernel: ds: 007b es: 007b ss: 0068 May 7 16:58:22 home01 kernel: Process scsi_eh_2 (pid: 5052, threadinfo=ca606000 task=c8404db0) May 7 16:58:22 home01 kernel: Stack: c16b8610 c16b8610 c16b8610 c028949a 00000000 d896ae6c ca606ecc c03a9c20 May 7 16:58:22 home01 kernel: ded8e800 00000282 00000000 00000000 df85147f c035873e c78d6df0 c78d6df0 May 7 16:58:22 home01 kernel: c78d6df0 ded8e800 ca606f74 00000206 ded8e200 ca606f74 ded8e818 00000000 May 7 16:58:22 home01 kernel: Call Trace: May 7 16:58:22 home01 kernel: [<c028949a>] cfq_next_request+0xef/0x122 May 7 16:58:22 home01 kernel: [<df85147f>] scsi_try_bus_reset+0xa3/0x380 [scsi_mod] May 7 16:58:22 home01 kernel: [<c035873e>] schedule+0x2ce/0x5f5 May 7 16:58:22 home01 kernel: [<df851b62>] scsi_eh_bus_reset+0x86/0x172 [scsi_mod] May 7 16:58:22 home01 kernel: [<df8512e2>] scsi_eh_bus_device_reset+0x16/0x110 [scsi_mod] May 7 16:58:22 home01 kernel: [<df85208a>] scsi_eh_ready_devs+0x30/0x4d [scsi_mod] May 7 16:58:22 home01 kernel: [<df8522e9>] scsi_unjam_host+0x14e/0x2d8 [scsi_mod] May 7 16:58:22 home01 kernel: [<df84d85f>] __scsi_iterate_devices+0xa0/0x17d [scsi_mod] May 7 16:58:22 home01 kernel: [<c011aac8>] default_wake_function+0x0/0xc May 7 16:58:22 home01 kernel: [<df8525c1>] scsi_error_handler+0x14e/0x205 [scsi_mod] May 7 16:58:22 home01 kernel: [<df852473>] scsi_error_handler+0x0/0x205 [scsi_mod] May 7 16:58:22 home01 kernel: [<c0101291>] kernel_thread_helper+0x5/0xb May 7 16:58:22 home01 kernel: Code: df 8b 46 04 8b 00 8b 40 4c c7 40 14 30 01 00 00 83 c4 20 89 f8 5b c1 f8 1f 5e f7 d0 5f 05 03 20 00 00 5d c3 8b 4b 28 66 bf f0 ff <8b> 81 4c 01 00 00 80 78 04 01 75 80 8b 53 2c 89 c8 e8 a5 16 63
