A few details on the machine: Acer 5820TG, it's got an Intel HD first gen + AMD radeon HD5650. It is a muxed switchable graphics system as far as I know

Looks like a duplicate of bug 61891. acpiphp is trying to remove the driver when the driver powers down the card because it thinks the card has been removed.

Just for the record, I'm on Acer 4820TG with ATI Mobility Radeon HD5470 and I'm experiencing the same exact issue described in https://bugs.freedesktop.org/show_bug.cgi?id=88927 I've not tried suggested patch because I'm not practical about kernel recompiling, and I'm on Xubuntu 15.04 with kernel 3.19.0-15-generic. Anyway I reported some logs and infos on my comment there, hope it can helps: https://bugs.freedesktop.org/show_bug.cgi?id=88927#c4
