Starting with kernel 3.0, Acer Aspire One A110 hangs on reboot
Hello,
Starting with kernel 3.0, my Acer Aspire One A110 hangs on reboot. Doing an internet search, I found that in git commit b49c78d4827be8d7e67e5b94adac6b30a4a9ad14 x86, reboot: Acer Aspire One A110 reboot quirk
the machine was made to reboot with the bios method. Well, it doesn't work here. I reverted that commit and found out that only the kbd method (reboot=k) works. So what I did is create a new quirks section for machines that only reboot with the kbd method and put the Aspire One into it.
No idea if this is the correct solution, all I know is my Aspire One now reboots again.
