Hrm... and we need those patches for blades that have a sil680 controller with no working PIO on the PCI host...
That's strange though. Somebody with knowledge of that HW (or specs) who can spot something ? Could it be an issue with timing ?
I don't have HW access to this machine. If somebody could send one to me I could do more investigation.
