Hi!

I found I cannot hibernate any more on the desktop after upgrading from Karmic to Lucid.
NB: I may be bit too much conservative but I waited until long after the alert that the version I used would not get any more support to turn to an LTS version. Keep it as long as it works! Prefering not to directly switch to 12.04, I used the 10.04 (Lucid Lynx) one.
I see a message saying that there is an issue in setting the state an usb device during that hibernation process, that involves the kernel routine rt73usb_set_device_state, and seems to cause moreover an issue with swap (NB: I have 2.8GB of ram and 7.5GB of swap!).
The message looks very much alike the bug reported at https://bugzilla.redhat.com/show_bug.cgi?id=700787 but the issue is that there is no such 2nd chance in my system as in his own (hit the key twice) and the system just hangs instead.
A guy posted a proposal for fix at http://www.spinics.net/lists/linux-usb/msg19444.html but it looks like the kernel has to be touched and this is something I would not like to do myself and expect that the Ubuntu developers take care in the context of an LTS.
Am I missing something?
Is there some (relatively) fresh kernel upgrade that I should download?
I tried to find on this forum someone having had this kind of message but could not.

Thanks in advance to any kernel expert to reply.

hibernaiton is connetced with drivers that are part of kernel.
i am not kernel expert, but i do know there are kernel PPA's that would install newer kernel.

i found that i have issues on hibernating in 12.04 and i also found it is a kernel bug so hopefully it will be resolved soon. still if it doesn't work for me it doesn't mean that it won't work for you. perhaps you should give 12.04 a try (maybe on a separate partition or install on USB stick/disk).

also your /swap size is a bit big.

What astonishes me is that this is a clear regression vs Karmic where I never faced this behaviour. I was under the impression that the non-regression verification work was the basis of the software package development work... Primum non nocere, as would the old motto go for medicine doctors.
And no, I don't want too much to switch to 12.04 so more since it seems it's not ripe yet. On the other hand, I saw a demo and it does not much look like I'm gonna like the evolution...

Thanks for the advice. BTW, I can't see why having a big swap would be an issue.
