I'm running an Opteron 2378 (2.2GHz) quad-core processor running a SP5100 southbridge, equivalent to an SB700-class chip. I am having the exact same problem and I've tried two different pairs of drives, different makes and models (started out with two WDC Caviar Green 750GB drives, moved to Seagate 1TB Barracudas (no XT, no LP)). It makes no difference; the system still crashes. For the record, the board is a Supermicro H8DI3-i-F board.
Likewise, the time and manner of problem is highly unpredictable. It appears to be a case of interrupt loss, and there is otherwise no hardware issue that I can discern with the drives themselves. I have yet to try pci=nomsi, but I have tried with pci=noacpi with identical results, a crashed system after a random period of time. However, I have my doubts whether this will work since, apparently, the AHCI controller is not using MSI-based interrupts (it shows AHCI connected as a IO-APIC-fasteoi interrupt). The ethernet controller does, however, use a PCI-MSI-edge interrupt, as does the PATA controller, which I do not use. If need be, I can furnish all the necessary data. I just need to know what is needed. Also, will the pci=nomsi item actually help me? I ask because, as I indicated, this controller apparently does not use such an interrupt. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/577796 Title: Filling disk with data leads to [sda] Unhandled error code.
