I found bug #232017 which sounds very similar to me. Setting swiotlb=128 fixed the problem in this case. I get an error similar to swiotlb=force. For values of 64 and 16 I get "BUG: soft lockup - CPU#1 stuck for 11s!", while 16 seems a bit more stable. With swiotlb=0, 2 or 8 I am back to the original kernel bug. I searched for the "soft lockup" bug, but couldn't find anything useful so far. acpi=off does not help. Somewhere a kernel >= 2.6.25 was suggested... - not sure if it is worth trying to compile. Most reports are X related, but I don't have X on the machine.
I'll keep on digging! ** Attachment added: "swiotlb_le128.tgz" http://launchpadlibrarian.net/16363800/swiotlb_le128.tgz -- linux-image-2.6.24-* w/ aic79xx crash under heavy I/O load https://bugs.launchpad.net/bugs/238118 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
