[Kernel-packages] [Bug 1262797] Re: acer-wmi module hangs laptop for 10 seconds on boot/modprobe
apport information ** Tags added: apport-collected ** Description changed: I have a Acer Aspire 7740, and noticed after installing that Ubuntu 13.10 (kernel 3.11.0-14) hangs for 10 seconds early in the boot process. It continues after that. The screen freezes and the fans start spinning very hard. The last dmesg line before the pause is a info message about acer-wmi. When modprobing this module after boot the same symptoms occur. Ubuntu hangs, and reacts normally after 10 seconds. So, clearly something is wrong with acer-wmi. Maybe it should not be loaded with this laptop version, or it has a bug in it.

[Kernel-packages] [Bug 1262797] Re: acer-wmi module hangs laptop for 10 seconds on boot/modprobe
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.13 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
