It looks to be some problem in shut down. Can you simply remove and re-insert the driver successfully? If it's your root disk driver, you'll have to do this from an initrd so as not to have root mounted from the eata controller. If the remove and reinsert fails, it means we have a problem in the driver shut down. If not, it's likely something kexec related.

After un-mounting file systems on the disk attached to the SCSI controller using the eata driver I could do a: modprobe -r eata but received the output of the attached dmesg log. Attempting to do modprobe eata after the previous modprobe -r eata resulted in a complete lock-up. Arthur.

Previously the eata driver just grabs and accesses eata PCI devices without implementing a PCI device driver, that causes troubles with latest IRQ related Commit 991de2e59090 ("PCI, x86: Implement pcibios_alloc_irq() and pcibios_free_irq()") changes the way to allocate PCI legacy IRQ for PCI devices on x86 platforms. Instead of allocating PCI legacy IRQs when pcibios_enable_device() gets called, now pcibios_alloc_irq() will be called by pci_device_probe() to allocate PCI legacy IRQs when binding PCI drivers to PCI devices. But the eata driver directly accesses PCI devices without implementing corresponding PCI drivers, so pcibios_alloc_irq() won't be called for those PCI devices and wrong IRQ number may be used to manage the PCI device. This patch implements a PCI device driver to manage eata PCI devices, so eata driver could properly cooperate with the PCI core. It also provides headroom for PCI hotplug with eata driver. It also represents non-PCI eata devices as platform devices, so it could be managed as normal devices.
