I get problem reports all the time, unfortunately, so far these have not been reproducible on the configurations and hardware I have. I am not denying there is a problem, but if I can't reproduce it, it takes a long time to fix.
Your problem seems to be missed/lost interrupts. If you display the contents of /proc/interrupts (ie cat /proc/interrupts), it will show whether level (good), edge (bad) or MSI (good if hw works) are being used.
Some workaround related things to try are:
1) Adding the module parameter "idle_timeout=10" will cause the driver to poll for status every 10ms. This is obviously a performance overhead but it can allow system to function.
2) Disabling MSI with either "pci=nomsi" on boot cmdline or by using module parameter "disable_msi=1". Message Signaled Interrupts are good, but it seems some chipsets don't work right.
