Bug ID: 89731 Summary: System doesn't boot on muxed IntelHD + HD5650 Product: Drivers Version: 2.5 Kernel Version: 3.17.4-301.fc21.x86_64 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: and.bernabei@gmail.com Regression: No
Created attachment 160521 --> https://bugzilla.kernel.org/attachment.cgi?id=160521&action=edit journal log
I installed Fedora21 (also tried updating the packages) but my system doesn't boot at all when in "Switchable" mode in BIOS.
The only way to have a successful boot is to use the VESA driver (nomodeset), or using the "Discrete" BIOS vga mode.
You can find the journal log attached, in contains useful call traces.
I am available to help with the debugging of this issue ;)

--- Comment #1 from Andrea and.bernabei@gmail.com --- 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

--- Comment #2 from Alex Deucher alexdeucher@gmail.com --- 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.

--- Comment #5 from Lorenzo S. lorenzo.stanco@gmail.com --- 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
