Karmic: Resume from hibernation needs resume= kernel line in GRUB

[Radu Cristian Fotescu]

Binary package hint: grub-pc

Either with the kernel from:
https://launchpad.net/ubuntu/karmic/+source/linux/2.6.30-4.5
or with the kernel from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30-rc4/
resuming from hibernation FREEZES and does NOTHING...

...unless:
(i) either you boot in single mode (recovery menu entry), in which case it resumes from swap as usual;
(ii) either you manually add to the kernel line in GRUB "resume=/dev/sda2" or whatever the swap is.

Resuming from suspend to ram is flawless w/o any hack.

Tested in Jaunty actually, to see that it fixes the Intel poor video performance (Bug #252094). It does (with the default X driver 2.6.3, it boosts glxgears from 177 FPS to 1537 FPS, still using EXA!).

Please don't ask me for the output of any command, nor logs. (Yes, I've read the guidelines. They're bullshit in this case. If I tell you that the car's brakes are broken, just go and look at then, and stop asking me about all kind of useless crap about the car.)
Please don't be robots and use your human brain.
It's extremely simple to TRY and see that a resume line fixes the issue.
Hopefully you'll find out why such a line is still necessary.

OK, uname -a:
2.6.30-4-generic #5-Ubuntu SMP Fri May 8 13:20:48 UTC 2009 i686 GNU/Linux

This is not a bug in the linux-meta package, moving to the linux package.

This appears to be a problem in the grub-pc package not placing the resume=XXXXX clause into the boot path.

I've done this manually but not very cleanly into /etc/grub.d/10_linux and after update-grub I can reboot from hibernate.

Recommend moving to grub-pc package.

Ahh, it seems I misunderstood the problem and the resume line shouldn't be
required on the current kernels.

Feel free to ignore my earlier comments.

Mark.

Hi Radu,

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? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/lucid.

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

apport-collect -p linux 375070

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.
