I'm hitting the WARN_ON(wakes > 2) in $SUBJECT when resuming from suspend on my laptop (quad-core i7 with HT on). Looks like the warning gets hit 36 times on resume. E.g.:
Call Trace: [<ffffffff813c13c0>] dump_stack+0x65/0x85 [<ffffffff810a7572>] warn_slowpath_common+0x82/0xd0 [<ffffffff810a76ca>] warn_slowpath_null+0x1a/0x20 [<ffffffff810ec8d8>] swake_up_all_locked+0x68/0x80 [<ffffffff810ecd40>] complete_all+0x30/0x50 [<ffffffff81506328>] device_resume_noirq+0x48/0x190 [<ffffffff8150648d>] async_resume_noirq+0x1d/0x50 [<ffffffff810ca188>] async_run_entry_fn+0x48/0x130 [<ffffffff810c14a9>] process_one_work+0x139/0x480 [<ffffffff810c1847>] worker_thread+0x57/0x490 [<ffffffff810c17f0>] ? process_one_work+0x480/0x480 [<ffffffff810c779d>] kthread+0xed/0x110 [<ffffffff810c76b0>] ? kthread_worker_fn+0x150/0x150 ehci-pci 0000:00:1a.0: System wakeup disabled by ACPI [<ffffffff817b0d0f>] ret_from_fork+0x3f/0x70 [<ffffffff810c76b0>] ? kthread_worker_fn+0x150/0x150 ---[ end trace 0000000000000002 ]--- This trace (and a similar one with device_resume) happens on all cpus so the trace info is kinda jumbled up. I'll try it with WARN_ON_ONCE instead tomorrow. I'll send the console log if you want it. Clark
