Bug Description

Boot hangs with 'lock' lights flashing in synchronisation. A hard boot is the only cure.
This occurs more than once daily & is very unpredictable. Consequently I am unable to reproduce this bug on either of two machines that it occurs on.

The last stable kernel was 2.6.35-23.

2.6.37-10 would not boot at all without acpi=off, so this is an improvement on that.

pip, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please report the results following https://wiki.ubuntu.com/DebuggingKernelBoot ? As well, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Christopher,

I'm pleased to tell you that this issue was cleared up in the final release.
I'm also pleased to say that the issue has not reoccured (for me at any
rate) since it was fixed. It may be worth noting that the hardware
involved initially (both machines) is no longer available to test on, so
perhaps that may be a factor. Having said that, the hardware
replacements are quite recent, but the issue had gone away anyway.

Regards,

Pip
