Hi, Thomas.

The unhandled irq 16 issue seems to be fixed by 4.0-rc1 commit "hpsa:
turn off interrupts when kdump starts".

Are the following patches suitable for stable now?

3b74729 hpsa: turn off interrupts when kdump starts
03741d9 hpsa: fix memory leak in kdump hard reset
859c75a hpsa: add missing pci_set_master in kdump path
132aa22 hpsa: refine the pci enable/disable handling

Cheers,
Vinson
