CPU scaling disabled on HP2133 under Jaunty

[David Trickett]

I have just updated to Ubuntu 9.04, kernel 2.6.28-14-generic and on startup it reports that CPU scaling is disabled. This happened on the last kernel update and was fixed some while later - I would have thought that they would have got it right this time!

Machine is a HP2133 mininote - cpu scaling is rather significant since this has a miserable battery life at the best of times!

Thanks for taking the time to report this bug. I cannot reproduce in my system, scaling works perfectly. It would help if you could provide more information about your system, and if any customization was done to it to alter the behavior.

Thanks again.

Thanks for coming back to me on this.

I have now managed to sort this out - inspired by your response I discovered
that at the last update my existing menu.lst had been replaced. CPU scaling
is an issue with this machine, and the helpful guidance at
https://wiki.ubuntu.com/LaptopTestingTeam/HP2133 suggested that the fix is
to incorporate "acpi_osi="!Windows 2006"" in the kernel line. I had this
previously but when my menu.lst was replaced this was lost - I have put it
back in and it now seems ok.

The reason I thought this was a bug is that at an earlier kernel update
despite the modification to the kernel line it still didn't work, and forum
traffic indicated that I was not the only one with this problem. However a
later update sorted this - I just thought that the same thing had happened
again.

Of course a fix which does not involve delving into startup files would be
nice!

Many thanks for your interest, and if you would like any more information
which might lead to a permanent fix please let me know.

David

PS I don't suppose you have any ideas about my digital photo frame crashing
the machine :-) ?

Thanks David, I am reassigning to the Ubuntu remix, so further action can be taken.

Also thanks for the report. Keep them coming. You might want to submit a separate report for the crashing or your photo app.
