-tycho kernel: ata1.00: configured for UDMA/33
+tycho kernel: ata1.00: configured for UDMA/100

That looks nice.

-tycho kernel: ata2: PATA max UDMA/100 cmd 0x170 ctl 0x376 bmdma 0x18C8 irq 15
-tycho kernel: scsi1 : ata_piix
-tycho kernel: ata2: port disabled. ignoring.
-tycho kernel: ATA: abnormal status 0xFF on port 0x177

So does that.

-tycho kernel: input: PS/2 Mouse as /class/input/input1
-tycho kernel: input: AlpsPS/2 ALPS GlidePoint as /class/input/input2

That's not so good.

Dmitry, do you have anything in there which might have caused that?

Perhaps hdaps-handle-errors-from-input_register_device.patch is triggering
for some reason. Fabio, it'd be useful if you could add this, see if it
