Hi! I have a problem, when my laptop just stands it freezes after some time.
In syslog I have a lot of messages like this: Jan 5 03:26:11 localhost kernel: [ 3488.016576] Device suspended Jan 5 03:26:11 localhost kernel: [ 3488.042232] [<c134ba9f>] ? credit_entropy_bits+0x1df/0x2b0 Jan 5 03:26:11 localhost kernel: [ 3488.042238] [<c134d8a9>] ? add_interrupt_randomness+0x109/0x1a0 Jan 5 03:26:11 localhost kernel: [ 3488.042245] [<c13c1105>] ? ehci_irq+0x1f5/0x2b0 Jan 5 03:26:11 localhost kernel: [ 3488.042252] [<c134d8dd>] ? add_interrupt_randomness+0x13d/0x1a0 Jan 5 03:26:11 localhost kernel: [ 3488.042260] [<c10b983d>] handle_irq_event_percpu+0x3d/0x180 Jan 5 03:26:11 localhost kernel: [ 3488.042266] [<c10b98a7>] ? handle_irq_event_percpu+0xa7/0x180 Jan 5 03:26:11 localhost kernel: [ 3488.042274] [<c10b99a5>] handle_irq_event+0x25/0x40 Jan 5 03:26:11 localhost kernel: [ 3488.042281] [<c10bbc10>] ? handle_simple_irq+0x60/0x60 Jan 5 03:26:11 localhost kernel: [ 3488.042289] [<c10bbc74>] handle_fasteoi_irq+0x64/0x100 Jan 5 03:26:11 localhost kernel: [ 3488.042296] [<c1042229>] handle_irq+0x69/0x80 Jan 5 03:26:11 localhost kernel: [ 3488.042298] <IRQ> [<c1041b17>] do_IRQ+0x37/0xd0 Jan 5 03:26:11 localhost kernel: [ 3488.042310] [<c15609ec>] common_interrupt+0x2c/0x34 Jan 5 03:26:11 localhost kernel: [ 3488.042317] [<c10c007b>] ? rcu_gp_kthread+0xfb/0x590 Jan 5 03:26:11 localhost kernel: [ 3488.042324] [<c13f13af>] ? cpuidle_enter_state+0x6f/0x160 Jan 5 03:26:11 localhost kernel: [ 3488.042332] [<c13f155f>] cpuidle_enter+0xf/0x20 Jan 5 03:26:11 localhost kernel: [ 3488.042338] [<c10a898c>] cpu_startup_entry+0x1fc/0x2f0 Jan 5 03:26:11 localhost kernel: [ 3488.042346] [<c155666d>] rest_init+0x5d/0x60 Jan 5 03:26:11 localhost kernel: [ 3488.042353] [<c176ab6b>] start_kernel+0x3a6/0x3ac Jan 5 03:26:11 localhost kernel: [ 3488.042361] [<c176a5e4>] ? set_init_arg+0x49/0x49 Jan 5 03:26:11 localhost kernel: [ 3488.042368] [<c176a360>] i386_start_kernel+0x12e/0x131 Jan 5 03:26:11 localhost kernel: [ 3488.042371] ---[ end trace 0dc8971a83e5fd4c ]--- Jan 5 03:26:11 localhost kernel: [ 3488.052457] [drm:__gen6_gt_force_wake_get] *ERROR* Timed out waiting for forcewake old ack to clear.

On genkernel everything working well, so I guess the problem is with kernel configuration.
