Right, we already happened upon pci=nomsi and have been using that since we first experienced the lockups.
Unfortunately, nearly all the nodes we experienced this with were put into production (with pci=nomsi) and we don't have 5T of storage to spare any more. I was able to find one node with 3T of storage and spent some time yesterday trying to reproduce this with the kernel we were running at the time (linux-image-2.6.24-19-server-2.6.24-19.36) and couldn't reproduce the lockups. I'm not sure what to say; we definitely experienced the lockups and pci=nomsi definitely put a stop to them, so I'm puzzled that I wasn't able to reproduce given a couple of hours. Close this if you need to, but I just don't have the time now to pursue further. -- MSI-X support in qla2xxx causes reproducible hangs under moderate I/O load https://bugs.launchpad.net/bugs/268242 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
