I have an HP Proliant DL380-G6 (dual Xeon E5540 @ 2.53GHz) with Xen 4.0.0 and dom0 Linux 2.6.32.12 x86_64 pvops and domU Linux kernel 2.6.30.1 x86_64. I'm using PCI passthrough (pci-stub) to pass my 4-port 8Gb PMC-Sierra Fibre Channel HBA to domU. After running I/Os for several hours, both dom0 and domU hangs and the Xen console shows the interrupt binding below where IRQ 66 shows in-flight=1 and mask set (---M). What's the best way to debug this problem? (XEN) IRQ: 66 affinity:00000000,00000000,00000000,00000001 vec:b9 type=PCI-MSI status=00000010 in-flight=1 domain-list=1: 79(---M), (XEN) IRQ: 67 affinity:00000000,00000000,00000000,00000004 vec:d9 type=PCI-MSI status=00000010 in-flight=0 domain-list=1: 78(----),
(XEN) IRQ: 68 affinity:00000000,00000000,00000000,00000010 vec:22 type=PCI-MSI status=00000010 in-flight=0 domain-list=1: 77(----), (XEN) IRQ: 69 affinity:00000000,00000000,00000000,00000040 vec:2a type=PCI-MSI status=00000010 in-flight=0 domain-list=1: 76(----),
(XEN) 07:00.3 - dom 1 - MSIs < 69 > (XEN) 07:00.2 - dom 1 - MSIs < 68 > (XEN) 07:00.1 - dom 1 - MSIs < 67 > (XEN) 07:00.0 - dom 1 - MSIs < 66 >
(XEN) MSI 66 vec=b9 fixed edge assert phys cpu dest=00000000 mask=0/0/-1 (XEN) MSI 67 vec=d9 fixed edge assert phys cpu dest=00000004 mask=0/0/-1 (XEN) MSI 68 vec=22 fixed edge assert phys cpu dest=00000002 mask=0/0/-1
(XEN) MSI 69 vec=2a fixed edge assert phys cpu dest=00000006 mask=0/0/-1 Thanks. Dante
