the spin-up takes a few seconds here under suspend/resume simulation:
| ata1: waiting for device to spin up (7 secs) | Restarting tasks ... done.
[5-10 seconds pass]
| ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) | ata1.00: configured for UDMA/100 | SCSI device sda: 156301488 512-byte hdwr sectors (80026 MB) | sda: Write Protect is off | sda: Mode Sense: 00 3a 00 00 | SCSI device sda: write cache: enabled, read cache: enabled, doesn't support DPO or FUA
with real resume it takes even longer time - but i dont see where the delays come from in that case - i suspect it's SATA.
i'm also getting this WARN_ON() from e1000:
BUG: at drivers/pci/msi.c:611 pci_enable_msi() [<c01061bd>] show_trace_log_lvl+0x19/0x2e [<c01062b6>] show_trace+0x12/0x14 [<c01062cc>] dump_stack+0x14/0x16 [<c024fcc4>] pci_enable_msi+0x6d/0x203 [<c02b709e>] e1000_request_irq+0x2e/0xe2 [<c02bb742>] e1000_resume+0x7f/0xef [<c0249a68>] pci_device_resume+0x1a/0x44 [<c02b39ec>] resume_device+0xf7/0x16f [<c02b3adb>] dpm_resume+0x77/0xcb [<c02b3b69>] device_resume+0x3a/0x51 [<c014e669>] enter_state+0x193/0x1bb [<c014e712>] state_store+0x81/0x97 [<c01b68bc>] subsys_attr_store+0x20/0x25 [<c01b6feb>] sysfs_write_file+0xce/0xf6 [<c017e16b>] vfs_write+0xb1/0x13a [<c017e899>] sys_write+0x3d/0x61 [<c0105220>] syscall_call+0x7/0xb
seems harmless because it seems to work fine.
