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. I will add a dmesg from a boot with acer-wmi enabled. - WORKAROUND: I blacklisted acer-wmi in /etc/modprobe.d/blacklist.conf and - updated initramfs. Now ubuntu boots as it should without hanging. No - functionality appears to be lost. Bluetooth and wifi work, also the - volume keys. + WORKAROUND: I blacklisted acer-wmi in /etc/modprobe.d/blacklist.conf and updated initramfs.
