Is is possible the SRIOV option is causing trouble? I don't see a BIOS option to disable that setting on this server like I have on some others. Any other ideas to get this working?I do not think the SRIOV is the problem here. I do notice that isci(4) does not explicitly enable PCI busmaster, which will cause problems with PCI passthrough. I've attached a patch that rectifies that issue. I'm not certain that is the root cause of the interrupt resource allocation failure though. Could you: 1) Apply the attached patch and retest. 2) If you still see the resource allocation failure, reboot in verbose mode and provide the resulting dmesg output. Thanks, -Jim
Thanks for the patch although the same error still persists. Here is the verbose boot log:
