Don't know if this is relevant. I ran dmesg upon logging back in and this is what it reports: [ INFO: possible circular locking dependency detected ] 2.6.33.2-57.fc13.i686.PAE #1 ------------------------------------------------------- kacpi_hotplug/24 is trying to acquire lock: (kacpid){+.+.+.}, at: [<c04565a8>] flush_workqueue+0x0/0x94 but task is already holding lock: ((&dpc->work)){+.+.+.}, at: [<c0455e7d>] worker_thread+0x15d/0x262 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 ((&dpc->work)){+.+.+.}: [<c046ab9b>] __lock_acquire+0xa23/0xb89 [<c046ad94>] lock_acquire+0x93/0xb1 [<c0455eb9>] worker_thread+0x199/0x262 [<c04592d8>] kthread+0x6f/0x74 [<c04091c2>] kernel_thread_helper+0x6/0x10 -> #0 (kacpid){+.+.+.}: [<c046aa9d>] __lock_acquire+0x925/0xb89 [<c046ad94>] lock_acquire+0x93/0xb1 [<c04565f4>] flush_workqueue+0x4c/0x94 [<c0607e24>] acpi_os_wait_events_complete+0x12/0x1e [<c0607e4c>] acpi_os_execute_deferred+0x1c/0x2d [<c0455ebf>] worker_thread+0x19f/0x262 [<c04592d8>] kthread+0x6f/0x74 [<c04091c2>] kernel_thread_helper+0x6/0x10 other info that might help us debug this: 2 locks held by kacpi_hotplug/24: #0: (kacpi_hotplug){+.+...}, at: [<c0455e7d>] worker_thread+0x15d/0x262 #1: ((&dpc->work)){+.+.+.}, at: [<c0455e7d>] worker_thread+0x15d/0x262 stack backtrace: Pid: 24, comm: kacpi_hotplug Not tainted 2.6.33.2-57.fc13.i686.PAE #1 Call Trace: [<c07c437d>] ? printk+0x14/0x17 [<c0469e43>] print_circular_bug+0x91/0x9d [<c046aa9d>] __lock_acquire+0x925/0xb89 [<c046abde>] ? __lock_acquire+0xa66/0xb89 [<c046ad94>] lock_acquire+0x93/0xb1 [<c04565a8>] ? flush_workqueue+0x0/0x94 [<c04565f4>] flush_workqueue+0x4c/0x94 [<c04565a8>] ? flush_workqueue+0x0/0x94 [<c0607e24>] acpi_os_wait_events_complete+0x12/0x1e [<c0607e4c>] acpi_os_execute_deferred+0x1c/0x2d [<c0455ebf>] worker_thread+0x19f/0x262 [<c0455e7d>] ? worker_thread+0x15d/0x262 [<c0607e30>] ? acpi_os_execute_deferred+0x0/0x2d [<c0459654>] ? autoremove_wake_function+0x0/0x34 [<c0455d20>] ? worker_thread+0x0/0x262 [<c04592d8>] kthread+0x6f/0x74 [<c0459269>] ? kthread+0x0/0x74 [<c04091c2>] kernel_thread_helper+0x6/0x10 ACPI: \_SB_.GDCK - undocking pulseaudio used greatest stack depth: 4848 bytes left pulseaudio used greatest stack depth: 4112 bytes left thinkpad_acpi: EC reports that Thermal Table has changed ACPI: \_SB_.GDCK - docking usb 1-5: new high speed USB device using ehci_hcd and address 5 usb 1-5: New USB device found, idVendor=04b3, idProduct=4485 usb 1-5: New USB device strings: Mfr=0, Product=0, SerialNumber=0 hub 1-5:1.0: USB hub found hub 1-5:1.0: 4 ports detected e1000e: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. 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 '13'. 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 13'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 13 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 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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.
