Sounds like a classic BIOS bug. This should be reported to Lenovo, and probably we should blacklist x2APIC on this machine. What does "dmidecode" show?

Will post a kernel patch to blacklist x2apic enabling on this system, once I figure out what I need to use for the blacklist. It looks like even some (not all) T420's are affected. I'm fairly certain I'm seeing this bug on Ubuntu "quantal", kernel package 3.4.0-3-generic (x86_64). Since the 3.4 release candidates started landing in the Ubuntu repos, I had fairly consistent boot hangs on my Thinkpad T500. I've just disabled VT-d in my BIOS and so far two out of two boots succeeded. I have the latest available BIOS installed (3.24, from December 2011). I'm experiencing the same thing on a Lenovo Thinkpad L520. I had previously thought it was a bug in any 3.2.x kernel or later because that's when I started having problems but 3.2.x and 3.3.x kernels are working now with CONFIG_X86_X2APIC=n. That option wasn't present in the Archlinux kernel configs before 3.2.0. Am I missing out on anything by not being able to enable x2apic? I'm using the latest BIOS (8GET39WW 1.16 4/3/2012). *** Bug 34262 has been marked as a duplicate of this bug. *** Confirmed to still be an issue on the W520 with bios 1.39, kernel 3.6.2. Current workarounds I have tried that work: 1) Use integrated graphics only 2) Use Optimus with bumblebee 3) Use 32-bit instead of 64-bit 4) Disable VT-D in the bios 5) intel_iommu=off Please ignore the previous workarounds in comment 10. Only 1 Seems and 4 seem to work consistently. Created attachment 84071 [details]

From the looks of it it, it is specifically the combination of these Thinkpads with Nvidia discrete graphics that is causing problems, i.e. the problem is in the Nvidia-specific part of the BIOS. I don't know if there is any sane way to qualify this based on a PCI quirk or something like that, though.

0001-x86-apic-Blacklist-x2apic-when-Nivida-graphics-enab.patch
Set blacklist x2apic when Nivida graphics enabled on some platforms: like ThinkPad W520 and ThinkPad T420.
I do not add quirk at arch/x86/kernel/early_quirks.c::early_quirks, because we only need check the Nivida graphics enabled or not at when issued platform detected like ThinkPad W520 and ThinkPad T420 which have x2apic capability.

This bug affects my laptop which doesn't have nvidia graphics. Thinkpad L520 with intel graphics only.

Actually I checked one T520 with Nvidia graphics, it seems x2apic works well. Now it is very confusing now. my test: t420 without nvidia chipset, works with x2apic. t510 with nvidia chipset, works with x2apic. BIOS versions? T510 or T520? T510 is a completely different box... Created attachment 88481 [details] x86-apic-Blacklist-x2APIC-on-some-platforms.patch x86,apic: Blacklist x2APIC on some platforms. Refer to bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/922037 T420 with Nvidia graphics: The BIOS version from: 83ET63WW(1.33) to 83ET72WW (1.42 ), the issue always shows. T420 without Nvidia graphics, the issue disappears. So blacklist x2apic on T420 only Nvidia graphics enabled. Thinkpad T520 with Nivida graphics and L520 without Nvidia graphics, both of them have the issue, so blacklist them for a simple solution. Hi Yinghai, When will you push your patch to kernel? http://git.kernel.org/?p=linux/kernel/git/yinghai/linux-yinghai.git;a=patch;h=de38757e964cfee20e6da1977572a2191d7f4aa0?

Thanks Thanks a lot Yinghai! I have just posted the patch to LKML. Thanks -Youquan Hi Yinghai, Can you get your patch http://git.kernel.org/cgit/linux/kernel/git/yinghai/linux-yinghai.git/diff/?id=de38757e964cfee20e6da1977572a2191d7f4aa0 upstream and then take the x2APIC fix patch http://lkml.org/lkml/2012/12/18/1 to upstream. After that, we can close this bug. Thanks -Youquan One additional solution seems to be to disable CSM in the UEFI configuration, without the additional need to specify 'nox2apic' or to disable VT-d. With CSM on, I otherwise observe the same issues reported above on my T430. Thus the following configurations work in my machine with discrete graphics: 1) CSM off 2) CSM on, 'nox2apic' kernel parameter 3) CSM on, VT-d off Unfortunately, the Lenovo Forums claim that CSM is required if you are dual-booting Windows 7 or lower on these ThinkPads, so turning it off may not be viable for everyone. For a pure Linux setup it's not required, though. Created attachment 106481 [details]

dmesg of working T430 with CSM off, x2apic on
I'm getting the same early boot hang with a Lenovo W530 on which I have VT-d enabled, and adding nox2apic to the commandline resolves the issue. This is not on a vanilla kernel, but I'm pretty sure that there is a problem with the W530 across all distros, so it seems the kernel should blacklist the W530 from using x2apic if Discrete Graphics are detected. At least for the current BIOS version (2.53) -- not sure if upgrading to the latest BIOS (2.59) will change anything. Steps to reproduce: 1. BIOS: - Configure for Discrete Graphics - Enable VT-x and VT-d under Security -> Virtualization 2. Use Nvidia driver 3. Configure kernel commandline *without* nox2apic 4. Boot Fedora 5. Early boot hang when udev becomes active, close to the likely unrelated "Could not configure common clock" message Boot hang is 100% reproducible with the S/W versions shown below. Option A to avoid boot hang (preferred): Steps as above, but add nox2apic to kernel commandline Option B to avoid boot hang: Steps as above, but disable VT-d in BIOS Digging further, I found the following related bugs, and infos [2] on the solution combining VT-x + VT-d with the nox2apic kernel parameter, which is preferable to disabling VT-d: [1] https://bugzilla.kernel.org/show_bug.cgi?id=43054 (this thread) [2] https://lkml.org/lkml/2011/5/23/196 [3] https://groups.google.com/forum/?fromgroups#!topic/fa.linux.kernel/iCAzjSyIHdI [4] http://forums.lenovo.com/t5/W-Series-ThinkPad-Laptops/W520-BIOS-Bug-Please-fix-or-comment-Lenovo/td-p/802085 [5] http://forums.lenovo.com/t5/Linux-Discussion/W520-Debian-64-bit-Testing-VT-enabled/td-p/671621 Installed BIOS, kernel and driver --------------------------------- # dmidecode -s bios-version && dmidecode -t11 G5ET93WW (2.53 ) # dmidecode 2.12 SMBIOS 2.7 present.

Use Nvidia driver Have you tried nouveau? I'm also using a W530 with VT-x, VT-d, and discrete graphics without the nox2apic parameter and experiencing no issues with the nouveau driver. It does not seem to matter which UEFI/Legacy setting is chosen. I normally boot with UEFI only, with CSM support, but have tried all of the UEFI supporting options. # dmidecode -s bios-version && dmidecode -t11 G5ET97WW (2.57 ) # dmidecode 2.12 # SMBIOS entry point at 0xdf69e000 SMBIOS 2.7 present. # uname -r 3.16.3-1-ARCH This affects W-530 as well. Adding nox2apic to grub config works around this. I'm using discrete mode with Nvidia blob, but nouveau has heat and performance issues still. I'm running into exactly the same problem with a W530 using the nouveau driver, VT-d enable, and discrete graphics (obviously). I have to pass the nox2apic parameter or the system locks up, just as others have stated. $ sudo dmidecode -s bios-version && sudo dmidecode -t11 && uname -r G5ET99WW (2.59 ) # dmidecode 2.12 # SMBIOS entry point at 0xdf69e000 SMBIOS 2.7 present. What is necessary to get the quirk included in the mainline kernel? 4.0.4-2-ARCH I can confirm that disabling CSM allows for the removal of the nox2apic parameter on the W530 even with both VT-d and discrete graphics enabled. |
