Yesterday it hangs again after pressing quickly the power button after resume.
Usually, the screen shows a text output during a second just after press the power button to resume. It is some like this (I'm not sure): irq 16: nobody cared (try booting with the "irqpoll" option) Pid: 0, comm: swapper Not tainted 2.6.28-18-generic #60-Ubuntu Call Trace: [<c04fe0f6>] ? printk+0x18/0x1a [<c017fff7>] __report_bad_irq+0x27/0x90 [<c01801be>] note_interrupt+0x15e/0x1a0 [<c017ed89>] ? handle_IRQ_event+0x39/0x70 [<c0180783>] handle_fasteoi_irq+0xa3/0xd0 [<c015ba37>] ? tick_check_idle+0x17/0x30 [<c010684e>] do_IRQ+0x7e/0xa0 [<c0153029>] ? hrtimer_start_range_ns+0xe9/0x1e0 [<c01051f3>] common_interrupt+0x23/0x30 [<c015007b>] ? posix_cpu_timer_create+0xab/0x100 [<c015bb1e>] ? tick_nohz_stop_sched_tick+0xce/0x380 [<c01051f3>] ? common_interrupt+0x23/0x30 [<c010281a>] cpu_idle+0x2a/0xd0 [<c04ee78e>] rest_init+0x4e/0x60 handlers: [<c03b7be0>] (usb_hcd_irq+0x0/0x90) [<f80157f0>] (azx_interrupt+0x0/0x140 [snd_hda_intel]) Disabling IRQ #16 pci 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 pci 0000:00:02.0: setting latency timer to 64 PM: resume devices took 1.220 seconds PM: Finishing wakeup.

So I was wrog. Maybe isn't hardware/BIOS problem. It could be solved with a kernel patch or adding 'irqpoll' to the boot. I will try adding the 'irqpoll' option to the kernel during booting.
