The device is just not returning the IO requests in time. I've checked if there are any known quirks for this particular device but it doesn't seem to be the case. A bit of searching on the IRQ setup I found some discussions on the VMD MSI-X domain remapping and some performance impact. Anyway, not sure if this is could be a problem here. Also a good candidate for troubles is PCI bus power management. I suggest you try some some of the kernel knobs if they address the problem, e.g. msi_remap=off pci=noacpi and see if it changes anything. -- You are receiving this mail because: You are the assignee for the bug.
