[Bug 653238] Re: maverick kernel 2.6.35-22 panics when booting on Dell Precision T3500
*** This bug is a duplicate of bug 647043 *** https://bugs.launchpad.net/bugs/647043 This is a different problem from bug #64703. In this problem, the Dell T3500 panics when we move a USB device into an e820-reserved area. There's a patch upstream that fixes this (commit 4dc2287c1805e7fe8a7cb90bbcd44abee8cdb914, see https://bugzilla.kernel.org/show_bug.cgi?id=16228). In bug #647043, Dell 1536 we also move USB devices, but the new address is not in an e820-reserved area, and the machine doesn't panic. The USB devices just don't work. We don't understand this problem yet (see https://bugzilla.kernel.org/show_bug.cgi?id=31602). Coincidentally, the same workaround, pci=nocrs, works for both bugs. ** Bug watch added: Linux Kernel Bug Tracker #31602 http://bugzilla.kernel.org/show_bug.cgi?id=31602 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/653238 Title: maverick kernel 2.6.35-22 panics when booting on Dell Precision T3500 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/653238/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi, By adding the option pci=nocrs, I have not seen real side effect. The only strange thing I can see are some text furtively displayed at the startup and the shutdown of Ubuntu, but nothing that affect the user. -- maverick kernel 2.6.35-22 panics when booting on Dell Precision T3500 https://bugs.launchpad.net/bugs/653238 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

I'm also affected by this bug on my T3500. Is there any other side effect of the pci=nocrs option besides fixing this bug? -- maverick kernel 2.6.35-22 panics when booting on Dell Precision T3500 https://bugs.launchpad.net/bugs/653238 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

I have the same identical problem as Matt (and Trigger, see: https://bugs.launchpad.net/ubuntu/+bug/659149). Same DELL Precision T3500 there is a new A08 BIOS dated 9/17/10 available from Dell, which I'll install as soon as I am done posting. http://support.dell.com/support/downloads/download.aspx?fileid=416864 however... found this too in https://bugzilla.kernel.org/show_bug.cgi?id=16228 FYI: I just updated my T3500 to the latest BIOS A08 from Dell. It still doesn't boot 2.6.34 without the proposed patches. So still no BIOS fix... I'll have to recall how to apply patches and compile the kernel, last time I've done it was years ago RHEL 5 or 6, so spoiled now by Ubuntu found this yet in another thread: https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/647043/comments/14 which has a link to a patched test kernel, with the same list of patches: I had Lisa do a series of tests. We subsequently discovered a series of patches that have been submitted upstream but are a bit invasive (ie. they won't land in upstream 2.6.36, and will likely have to wait for 2.6.37). http://marc.info/?l=linux-kernelm=128476278029918w=2 Patch : https://patchwork.kernel.org/patch/189182/ Patch : https://patchwork.kernel.org/patch/189232/ Patch : https://patchwork.kernel.org/patch/189242/ Patch : https://patchwork.kernel.org/patch/189252/ I've subsequently built a test kernel with the above patches applied. Lisa has confirmed this fixes the issue and the USB ports work with this test kernel. The test kernel can be found at the following: http://people.canonical.com/~ogasawara/lp647043/i386/ I'll have to discuss with the Ubuntu Kernel SRU team if they will qualify for a Stable Release Update to Maverick. -avi -- maverick kernel 2.6.35-22 panics when booting on Dell Precision T3500 https://bugs.launchpad.net/bugs/653238 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

the A08 BIOS update did not resolve the problem. pci=nocrs does work with the Ubuntu kernel. did not yet try the test patched kernel (got to get some real work done...) -avi -- maverick kernel 2.6.35-22 panics when booting on Dell Precision T3500 https://bugs.launchpad.net/bugs/653238 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
