Regarding the IRQ issue...

I agree that IRQ 11 is probably the problem. It was when I was using the old AHCI driver.
Your log of lshw states Linux is using IRQ/GSI 19 for pci@...332...:00:11.0 in line 151. Unfortunately, the device surprisingly lacks the MSI capability and apparently the IRQ routing information in the ACPI table is wrong resp. incorrectly interpreted by our acpi_drv. Maybe you could try to hard-wire the IRQ setting for this device to 19 in pci_drv and give it a shot.
