Message-ID: <20061129190815.GK2418@jukie.net> Date: Wed, 29 Nov 2006 14:08:15 -0500 From: Bart Trojanowski <bart@...ie.net> To: linux-kernel@...r.kernel.org Subject: Re: 2.6.18.3 soft lockups and 2.6.19-rc6 rwlock OOPs on SMP x86-64 One more update. I rebuilt 2.6.19-rc6 and turned off CONFIG_PREEMPT_BKL. It didn't help much. I am still getting BUG dumps from the kernel, however they don't cause freezes immediately. It takes a few minutes of console output before the computer stops responding to my input. As I was writing the above I tried building again under 2.6.19-rc6. The kernel OOPSed with a NULL pointer dereference. -Bart [ 1273.206537] Unable to handle kernel NULL pointer dereference at 0000000000000005 RIP: [ 1273.212025] [<ffffffff8100784f>] _raw_spin_lock+0x1f/0x140 [ 1273.220130] PGD 15465067 PUD 15427067 PMD 0 [ 1273.224477] Oops: 0000 [1] SMP [ 1273.227681] CPU 0 [ 1273.229733] Modules linked in: ide_cd cdrom binfmt_misc ipv6 container battery asus_acpi ac nfs lockd sunrpc af_packet rtc parport_pc lp parport [ 1273.243012] Pid: 13785, comm: make Not tainted 2.6.19-rc6-xenon64-smp.10 #1 [ 1273.249991] RIP: 0010:[<ffffffff8100784f>] [<ffffffff8100784f>] _raw_spin_lock+0x1f/0x140 [ 1273.258313] RSP: 0018:ffffffff8155af38 EFLAGS: 00010092 [ 1273.263649] RAX: 0000000000009e40 RBX: 0000000000000001 RCX: 0000000000000000 [ 1273.270802] RDX: 0000000000000001 RSI: ffffffff814f7d80 RDI: 0000000000000001 [ 1273.277955] RBP: ffffffff81447060 R08: 0000000000000001 R09: 0000000000000000 [ 1273.285107] R10: 0000000000004008 R11: 0000000000000000 R12: 0000000000000000 [ 1273.292253] R13: 0000000000000001 R14: 00000000ffffffff R15: 0000000000000001 [ 1273.299407] FS: 00002b6c23c6cae0(0000) GS:ffffffff814f7000(0000) knlGS:0000000000000000 [ 1273.307530] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b [ 1273.313296] CR2: 0000000000000005 CR3: 0000000014066000 CR4: 00000000000006e0 [ 1273.320442] Process make (pid: 13785, threadinfo ffff8100132d2000, task ffff81001845f0c0) [ 1273.328651] Stack: ffffffff814f7d80 ffffffff81447060 0000000000000000 0000000000000001 [ 1273.336784] 00000000ffffffff ffffffff810b6f09 ffffffff8106624c ffffffff81554c30 [ 1273.344292] 0000000000000020 0000000000000000 ffff8100185cbda0 ffffffff81073f0a [ 1273.351584] Call Trace: [ 1273.354269] <IRQ> [<ffffffff810b6f09>] handle_edge_irq+0x119/0x150 [ 1273.360672] [<ffffffff8106624c>] call_softirq+0x1c/0x28 [ 1273.366007] [<ffffffff81073f0a>] do_IRQ+0x8a/0xe0 [ 1273.370819] [<ffffffff81065641>] ret_from_intr+0x0/0xa [ 1273.376066] <EOI> [<ffffffff81069f67>] __mutex_lock_slowpath+0x1d7/0x1f0 [ 1273.382990] [<ffffffff81023409>] dbg_redzone1+0x19/0x30 [ 1273.388323] [<ffffffff810cfa45>] pipe_read+0x75/0x400 [ 1273.393485] [<ffffffff8106b129>] _spin_unlock_irq+0x9/0x10 [ 1273.399079] [<ffffffff8100ca1f>] do_sync_read+0xcf/0x120 [ 1273.404503] [<ffffffff810a06a0>] autoremove_wake_function+0x0/0x30 [ 1273.410787] [<ffffffff8103f739>] remove_wait_queue+0x19/0x60 [ 1273.416554] [<ffffffff8106b129>] _spin_unlock_irq+0x9/0x10 [ 1273.422151] [<ffffffff8102b33a>] do_sigaction+0x1aa/0x1d0 [ 1273.427656] [<ffffffff8100b08b>] vfs_read+0xdb/0x1a0 [ 1273.432733] [<ffffffff81011db3>] sys_read+0x53/0x90 [ 1273.437720] [<ffffffff8106511e>] system_call+0x7e/0x83 [ 1273.442967] [ 1273.444481] [ 1273.444482] Code: 81 7f 04 ad 4e ad de 74 0c 48 c7 c6 dc 30 3c 81 e8 1c c2 00 [ 1273.453619] RIP [<ffffffff8100784f>] _raw_spin_lock+0x1f/0x140 [ 1273.459577] RSP <ffffffff8155af38> [ 1273.463085] CR2: 0000000000000005 [ 1273.466569] <3>BUG: sleeping function called from invalid context at kernel/rwsem.c:20 [ 1273.474672] in_atomic():1, irqs_disabled():1 [ 1273.478984] [ 1273.478985] Call Trace: [ 1273.483002] <IRQ> [<ffffffff810a2e85>] down_read+0x15/0x30 [ 1273.488747] [<ffffffff81099b80>] blocking_notifier_call_chain+0x20/0x50 [ 1273.495484] [<ffffffff81015c52>] do_exit+0x22/0x8c0 [ 1273.500491] [<ffffffff8106b169>] _spin_lock_irqsave+0x9/0x10 [ 1273.506277] [<ffffffff811d17b6>] vgacon_set_cursor_size+0x36/0xf0 [ 1273.512494] [<ffffffff8106d809>] do_page_fault+0x7a9/0x8b0 [ 1273.518107] [<ffffffff81063908>] blk_run_queue+0x28/0x80 [ 1273.523546] [<ffffffff812561bb>] scsi_next_command+0x3b/0x60 [ 1273.529330] [<ffffffff8106b58d>] error_exit+0x0/0x84 [ 1273.534422] [<ffffffff8100784f>] _raw_spin_lock+0x1f/0x140 [ 1273.540035] [<ffffffff810b6f09>] handle_edge_irq+0x119/0x150 [ 1273.545817] [<ffffffff8106624c>] call_softirq+0x1c/0x28 [ 1273.551171] [<ffffffff81073f0a>] do_IRQ+0x8a/0xe0 [ 1273.556002] [<ffffffff81065641>] ret_from_intr+0x0/0xa [ 1273.561267] <EOI> [<ffffffff81069f67>] __mutex_lock_slowpath+0x1d7/0x1f0 [ 1273.568224] [<ffffffff81023409>] dbg_redzone1+0x19/0x30 [ 1273.573574] [<ffffffff810cfa45>] pipe_read+0x75/0x400 [ 1273.578754] [<ffffffff8106b129>] _spin_unlock_irq+0x9/0x10 [ 1273.584365] [<ffffffff8100ca1f>] do_sync_read+0xcf/0x120 [ 1273.589804] [<ffffffff810a06a0>] autoremove_wake_function+0x0/0x30 [ 1273.596108] [<ffffffff8103f739>] remove_wait_queue+0x19/0x60 [ 1273.601894] [<ffffffff8106b129>] _spin_unlock_irq+0x9/0x10 [ 1273.607505] [<ffffffff8102b33a>] do_sigaction+0x1aa/0x1d0 [ 1273.613030] [<ffffffff8100b08b>] vfs_read+0xdb/0x1a0 [ 1273.618124] [<ffffffff81011db3>] sys_read+0x53/0x90 [ 1273.623128] [<ffffffff8106511e>] system_call+0x7e/0x83 [ 1273.628393] [ 1273.629960] Kernel panic - not syncing: Aiee, killing interrupt handler!
