Dell Latitude E6520 (and E6220) do not reboot with 64 bit kernel

Two more notes:

 * shutdown -h works fine. Turns system off. Only reboot hangs.

 * in BIOS the boot mode is leagacy (the default) not UEFI.

Upstream recently added reboot=pci quirks for E6320, E5420 and E6420.

Hi Julian. Sounds great! Do you have an URL? Is it possible to try/force the quirk for E6[52]20 with something like pci.quirks=0x????:... as kernel boot param?

http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-oneiric.git;a=commit;h=b7798d28ec15d20fd34b70fa57eb13f0cf6d1ecd seems like a good summary. Try passing 'reboot=pci' as a kernel parameter.

reboot=pci fixes the 'always-hangs-on-reboot' of the Latitude E6520 with
natty (2.6.38-10) and oneiric (3.0.0-9) kernels.

As soon as the E6220 is back I'll test it also there.

Thx,
Achim

Hi Achim,

I've built a test kernel with reboot=pci quirk patches applied for the E6520 and E6220. If you could, please test on both of the affected systems and let me know your results.

http://people.canonical.com/~ogasawara/lp833705/

Hi Leann,

Summary: fixed the problem on E6520. Test E6220 when it's back in the Institute

Achim

I've tested your kernel with the Latitude E6520

root@lap-allee:~# uname -a
Linux lap-allee 3.0.0-10-generic #15~lp833705v1 SMP Fri Aug 26 14:40:17 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

and it reboots fine without reboot=pci on the cmdline:

root@lap-allee:~# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.0.0-10-generic root=UUID=8100885a-a17e-4b9c-8ef0-76863ac9868b ro quiet splash vt.handoff=7

Thanks Achim. Just curious how soon the the E6220 will be back in your possession to test? I'd like to send both patches upstream at the same time, but would like confirmation on the E6220 before I do. Thanks.

I've sent him an e-mail to ask him when he's back from the conference.

Achim

Hi Leann,
he'll be back with the laptop in two weeks, Mo, Sep 12th. So before I can't verify the E6220 patch.

As canonical certified the E6220 maybe you can ask https://launchpad.net/~brendan-donegan
if he has access to the E6220 and can do a quick test.

Thanks Achim.

I'll go ahead and submit the patch for the E6520 upstream and to the Ubuntu kernel. Once I can confirm the patch for the E6220 I'll submit that one as well. If you're able to get access to the E6220 before I am, please test and let me know your results. Thanks.

Hi Achim,

So I submitted this patch upstream but got some pushback from one of the maintainers, "we are starting to have something close to a full Dell product catalog in the system. I think we need to come up with something more systematic...". So I've gone ahead and sent this to the Ubuntu kernel team mailing list for consideration to carry this patch until a more systematic solution can be found which upstream will accept.

https://lists.ubuntu.com/archives/kernel-team/2011-August/016886.html

In the mean time, I think it would also be better to open up a separate bug report for the E6220 reboot issue (feel free to assign me to the bug and reference this bug). The reason I say this is because the E6220 will require a different patch (albeit similar). And if the patch for the E6520 is accepted for the Ubuntu kernel, this bug will be autoclosed and I still want to ensure we have a bug open to track the issue for the E6220. Thanks.

Two cents:
is there any channel to Dell you could go through and talk to the right people? Apparently their Optiplex line requires the same quirk with every new model (see open bugs 800660, 768039, 818933).

Hi Julian,

Thanks for the note to the other bugs. Definitely seems like a growing concern. I'll raise this on the mailing list and see if there are any contacts at Dell we might be able to reach.

In the mean time, the quirk patch for the E6520 has been applied. Marking this Fix Committed.

As requested in bug 838402, I've built a Natty test kernel with the patch for the E6520 applied. Please test and let me know your results. I can then submit for Natty SRU. Thanks.

http://people.canonical.com/~ogasawara/lp833705/natty/

Great! Your patched natty kernel fixes the 64bit reboot problem for E6520.

Tested without reboot=pci on cmdline

  current natty 2.6.38.11.48 -> reboot hangs
  your patched 2.6.38.11.51~lp... -> reboots without problems

Thx,
Achim
P.S. I test the E6220 next week, when as soon as I can borrow the laptop again.

I've sent the Natty SRU request to the Ubuntu kernel team mailing list:

https://lists.ubuntu.com/archives/kernel-team/2011-September/017119.html

Applied to Natty, marking Natty nomination Fix Committed.

The patched kernel also fixed the bug for me on an E6520. Thanks!

This bug is awaiting verification that the kernel for Natty in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-natty' to 'verification-done-natty'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Which natty kernel in proposed? I've add natty-propsed to sources.list. But apt-cache policy was not able to find
linux-image-2.6.38-11 or -12.

Achim

Hi Achim,

It should be the 2.6.38-12.51 kernel in the natty-proposed pocket which contains this fix. After adding natty-proposed to your sources.list, make sure to run sudo apt-get update.

https://launchpad.net/ubuntu/+source/linux/2.6.38-12.51

Ah, I'd used the german archive mirror. It had not synced obviously.

E6520 reboots with the 2.6.38-12.51 kernel.
Therefore I've changed the tag to verification-done-natty.
