Summary: Fan stays off and power button fails to work after hibernate and resume https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=186383 ------- Additional Comments From [EMAIL PROTECTED] 2006-10-31 02:59 EST ------- I use kernel-2.6.18-1.2798.fc6 on an HP compaq nc6000 laptop. My problem is _almost_ the same: - pm-hibernate causes the lowest fan speed setting to fail when on AC power: when using the AC adapter, the fan should always be running on lowest speed. Higher temperatures still trigger the higher fan speeds. N.B.: when not plugged in to AC, lowest fan speed works after resume (need to make sure the fan is off when running pm-hibernate). - pressing the "sleep" key on my laptop suspends it (S3). After resume, none of the fan speed settings work. - the pm-suspend script is unusable for me, since the laptop locks up on wake up. Playing with the fan controls in /proc/acpi/fan gives the following: - /proc/acpi/fan/C212/state is set to "on", which translates to lowest speed - /proc/acpi/fan/C211/state is set to "off", as are C210 and C20F - When echoing "on" to /proc/acpi/C211/state, the fan speeds up - Echoing "off" to any of the fan controls has no effect - Unplugging the AC adapter switches off the fan (C211 is still set to "on", while C212 is set to "off") - Plugging AC back in does _not_ switch on the fan - After about a minute, the fan switches back on (C211 has been automatically reset to "off") P.S. I should note that i2c has been disabled for this laptop, as per Bug # 193209. P.P.S. Ever since I use above kernel, I persistently get a backtrace on each resume.
