Kernel version 3.0 not supported

[John Cooper]

With the latest oneiric 3.0 kernel version

I get the following in /var/log/syslog

laptop-mode: Unhandled kernel version: 3.0 ('uname -r' = '3.0-1-generic')

I have added s "3.0");; to the file /usr/sbin/laptop_mode about line 506 so it reads as follows:

    case "$KLEVEL" in
     "2.4" ) ;;
     "2.6" ) ;;
     "3.0" ) ;;
     *)
      log "ERR" "Unhandled kernel version: $KLEVEL ('uname -r' = '$(uname -r)')" >&2
      exit 1
      ;;

This lets it work.

A new release is due any time soon. That will solve this problem.

Confirmed this bug in oneiric. It looks like it is fixed in laptop-mode-tools 1.58-1; we probably should merge up to 1.58-3.

[liberal-animation (liberal-animation)]

I did the above fix, and now I get a core dump on 3.0, and "Failed." for 2.6.35
I was getting the same error as OP.

[Christian Mertes (cmertes)]

"We probably should" at the end of August and that's it? Anyway, this bug is still there. I applied the workaround and got this:

"Bug No longer marked as fixed in versions laptop-mode-tools/1.58-1" & "Bug archived." - from the debian bug tracker.

I guess this means the status of "Fix-released" for debian on this bug is no longer valid. I don't seem to be able to follow the trail any further. :'-(

(for the record I'm trying to use laptop-mode-tools to stop folding@home stepping up my cpu scaling, and currently failing)

[Lorenzo Bettini (bettini)]

by applying the workaround I get a similar problem

[Mekk (marcin-kasperski)]

If I understand correctly, this problem is responsible for drastically shortened time on battery, lack of auto-hibernation on battery low, and higher temperature of my laptop – which I observe since upgrading to Ubuntu 11.10 – and which mostly render my laptop unusable on battery.

[Mekk (marcin-kasperski)]

The backtrace can be worked around by disabling this very module:

/etc/laptop-mode/conf.d/hal-polling.conf:

#CONTROL_HAL_POLLING="auto"
CONTROL_HAL_POLLING=0

After this pach laptop_mode starts/stops properly.

I am not sure about the impact of disabling HAL polling.

[piccobello (piccobello)]

I can confirm that the workaround proposed by John in the bug description,
together with the turnaround proposed by Mekk In Comment #8, work for
me. I still have to test the powerdrain of kernel 3.0, but it seems to have
reduced my battery life since 2.6
Using Kubuntu Oneiric, kernel 3.0.0-13.22, laptop-mode-tools 1.57-1ubuntu1

[Florian Rathgeber (florian-rathgeber)]

The fix seems not to have been backported to 11.10 Oneiric.

[Phillip Susi (psusi)]

Nor will it be. See http://wiki.ubuntu.com/StableReleaseUpdates
