The last kernel I used was 3.4 with halt=mwait parameter. If someone still uses the Thinkpad R51e I recommend kernel 2.6.23 (no EC problems) and the separate madwifi package (which supports wlan powersave mode). -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug.

https://bugzilla.kernel.org/show_bug.cgi?id=22332 --- Comment #27 from Vitus Jensen 2012-05-28 09:41:12 --- knoppix v6.7.1 shows a high wakeup rate, too. But that is kernel 3.0, finnix was the newest I could find. Meanwhile I experimented with kernel v3.4 and idle=xxx in the commandline, fully booted system (gnome, wlan, nfsclient): idle=mwait85 wakeups idle=halt 85 wakeups idle=poll 110 wakeups idle=nomwait low wakeups, system freeze (no idle) around 50.000 wakeups, system freeze The freezes might be related to https://bugzilla.kernel.org/show_bug.cgi?id=13155, I haven't backported the old EC driver to 3.4. While powertop does no longer report CPU entering any C-states the system is stable running idle=mwait since yesterday, suspends/resumes fine. Does this tell you something? Is this a workaround or the recommended way to use a tickless kernel in case of problems? -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug.

And output of powertop and /proc/interrupts is matching in this respect. I've unloaded ath5k and support and used the cable. The next powertop outputs show that the high wakeup count isn't related to a specific interrupt line, it even happens when there is no noticable interrupt activity.

https://bugzilla.kernel.org/show_bug.cgi?id=22332 --- Comment #12 from Bob Copeland 2010-11-10 05:24:39 --- I'm a bit confused, can you characterize the # of wakeups with/without ath5k? You seem to say unloading it drops the number of wakeups, but that it doesn't have a lot of interrupts? Or is the issue that #interrupts doesn't seem to correlate with wakeups as reported by powertop? /proc/interrupts output seems to show about 400 interrupts on that shared line for 10 seconds, so 40/s which is probably not too unusual if the card is actively receiving beacons with a few APs around. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug. -- The Next 800 Companies to Lead America's Growth: New Video Whitepaper David G.

But it's only growing by 40-50 interrupts/s and not 50.000. And the wakeups still occur after at5k is unloaded, only very seldom.

[Bug 22332] 10Ks of wakeups in tickless kernel
https://bugzilla.kernel.org/show_bug.cgi?id=22332 --- Comment #7 from Vitus Jensen 2010-11-08 16:23:51 --- The kernel already had CONFIG_PM_RUNTIME enabled and when powertop prompted to press 'P' to enable runtime power management I did so. When booting to console and unloading USB drivers (usbcore remains inuse, *hcd is unloaded) nothing changed. After unloading ath5k powertop reports ca. 40 wakeups/s, but occasional this skyrocks to 6.000 or more. There is no pattern, 1 min, 2 min, no high wakeup count for 5 minutes. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug.

Vitus, can you please try 2.6.36 kernel with CONFIG_PM_RUNTIME set and see if the problem still exist? -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug.
