I just ran into this problem. And I can confirm post #6, adding the pci=nocrs to grub.conf solves the problem. Another workaround is to boot an older kernel version, some 2.6.34.xxx.
https://bugzilla.kernel.org/show_bug.cgi?id=16228 tells of a patch for fixing this is available. And there they tell also, that there is no BIOS for the Dell T3500 available resolving the problem. So IMHO for ubuntu either the pci=nocrs should go into the grub.conf (for Dell T3500) or - preferred - the mentioned patch should be included ... ? -- Kernel Oops with Maverick in ahci_stop_engine https://bugs.launchpad.net/bugs/658560 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
