After resuming the second time the disk is not longer usable. After the first resume a simple "emacs -nw bla.txt" takes already ~45sec to launch, but there are no kernel messages. During the second resume the ATA interrupt gets disabled due to an unhandled interrupt. This is 100% reproducible. So I can provide as much info as needed. tglx Boot: SCSI subsystem initialized libata version 2.00 loaded. ata_piix 0000:00:1f.2: version 2.00ac7 ata_piix 0000:00:1f.2: MAP [ P0 P2 XX XX ] ata_piix 0000:00:1f.2: invalid MAP value 0 ACPI: PCI Interrupt 0000:00:1f.2[B] -> GSI 22 (level, low) -> IRQ 21 PCI: Setting latency timer of device 0000:00:1f.2 to 64 ata1: SATA max UDMA/133 cmd 0x18D0 ctl 0x18C6 bmdma 0x18B0 irq 21 ata2: SATA max UDMA/133 cmd 0x18C8 ctl 0x18C2 bmdma 0x18B8 irq 21 scsi0 : ata_piix PM: Adding info for No Bus:host0 ata1.00: ATA-7, max UDMA/133, 195371568 sectors: LBA48 NCQ (depth 0/32) ata1.00: ata1: dev 0 multi count 16 ata1.00: configured for UDMA/133 scsi1 : ata_piix PM: Adding info for No Bus:host1 scsi 0:0:0:0: Direct-Access ATA ST9100824AS 3.14 PQ: 0 ANSI: 5 PM: Adding info for scsi:0:0:0:0 SCSI device sda: 195371568 512-byte hdwr sectors (100030 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 SCSI device sda: 195371568 512-byte hdwr sectors (100030 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 sda: sda1 sda2 < sda5 > sda3 sd 0:0:0:0: Attached scsi disk sda 1st Suspend: ata_piix 0000:00:1f.2: suspend ACPI: PCI interrupt for device 0000:00:1f.2 disabled PIIX_IDE 0000:00:1f.1: suspend ....
