Description of problem: Version-Release number of selected component (if applicable): 2.6.17-1.2517.fc6 and 2.6.17-1.2530.fc6 How reproducible: Steps to Reproduce: 1. Boot, and the fireworks begin early on at "checking if image is initramfs..." 2. Even after booting, there's a ton more spewage, seemingly at random when doing things as simple as ssh/scp, and also when running the attached sysreport. Actual results: ####### checking if image is initramfs... ============================================= [ INFO: possible recursive locking detected ] --------------------------------------------- swapper/1 is trying to acquire lock: (&nc->lock){....}, at: [<ffffffff8020782c>] kmem_cache_free+0x1a1/0x26c but task is already holding lock: (&nc->lock){....}, at: [<ffffffff8020b47e>] kfree+0x1b3/0x27e other info that might help us debug this: 2 locks held by swapper/1: #0: (&nc->lock){....}, at: [<ffffffff8020b47e>] kfree+0x1b3/0x27e #1: (&parent->list_lock){....}, at: [<ffffffff802dae22>] __drain_alien_cache+0x37/0 x77 stack backtrace: Call Trace: [<ffffffff8026e77d>] show_trace+0xae/0x30e [<ffffffff8026e9f2>] dump_stack+0x15/0x17 [<ffffffff802a7f23>] __lock_acquire+0x135/0xa54 [<ffffffff802a8de3>] lock_acquire+0x4b/0x69 [<ffffffff8026774b>] _spin_lock+0x25/0x31 [<ffffffff8020782c>] kmem_cache_free+0x1a1/0x26c [<ffffffff802da9a8>] slab_destroy+0x12b/0x138 [<ffffffff802dab5f>] free_block+0x1aa/0x1ee [<ffffffff802dae48>] __drain_alien_cache+0x5d/0x77 [<ffffffff8020b49b>] kfree+0x1d0/0x27e [<ffffffff80968444>] free+0x9/0xb [<ffffffff80968461>] huft_free+0x1b/0x27 [<ffffffff8096961c>] inflate_dynamic+0x4f0/0x525 [<ffffffff80969b18>] unpack_to_rootfs+0x4c7/0x930 [<ffffffff80969fe6>] populate_rootfs+0x65/0xe7 [<ffffffff8026d710>] init+0x190/0x3cd [<ffffffff8026135e>] child_rip+0x8/0x12 DWARF2 unwinder stuck at child_rip+0x8/0x12 Leftover inexact backtrace: [<ffffffff80267a32>] _spin_unlock_irq+0x2b/0x31 [<ffffffff8026099c>] restore_args+0x0/0x30 [<ffffffff8036c696>] acpi_os_acquire_lock+0x9/0xb [<ffffffff8026d580>] init+0x0/0x3cd [<ffffffff80261356>] child_rip+0x0/0x12 it is ############## ############ sibling task PC pid father child younger older init S ffff8101442eda08 0 1 0 2 (NOTLB) ffff8101442eda08 ffff8101442ed988 ffffffff806c0d80 0000000000000008 ffff81013fc6a040 ffffffff80567e80 000000a047ea2983 0000000000015fe9 ffff81013fc6a228 ffff810100000000 ffffffff806c0d80 ffff8101442eda08 Call Trace: [<ffffffff80265886>] schedule_timeout+0x8c/0xb3 [<ffffffff8021204c>] do_select+0x470/0x4de [<ffffffff802e705b>] core_sys_select+0x1b7/0x266 [<ffffffff80217106>] sys_select+0x147/0x172 [<ffffffff8026040e>] system_call+0x7e/0x83 DWARF2 unwinder stuck at system_call+0x7e/0x83 Leftover inexact backtrace: migration/0 S ffff81013fc77e98 0 2 1 3 (L-TLB) ffff81013fc77e98 0000000100000296 0000000000000002 0000000000000001 ffff8101442ea040 ffffffff80567e80 000000a0598b50f5 000000000000119a ffff8101442ea228 ffff810100000000 0000000000000046 ffff81013fc77e78 Call Trace: [<ffffffff80246a22>] migration_thread+0x1a2/0x23f [<ffffffff802353fe>] kthread+0x100/0x136 [<ffffffff8026135e>] child_rip+0x8/0x12 DWARF2 unwinder stuck at child_rip+0x8/0x12 Leftover inexact backtrace: [<ffffffff80267a32>] _spin_unlock_irq+0x2b/0x31 [<ffffffff8026099c>] restore_args+0x0/0x30 [<ffffffff802352fe>] kthread+0x0/0x136 [<ffffffff80261356>] child_rip+0x0/0x12 ######### Expected results: No spewage Additional info: I'm seeing all of this behavior on an HP xw9300 workstation
