Hey fellow Archers!
I've got a workstation with an AMD FirePro V4900 card that has been running fine with catalyst-test from the AUR for months now. For my current project, I am doing some heavy-duty OpenCL computation, and thus decided to buy the beefier FirePro W5000 and use it as a dedicated OpenCL GPU while keeping the V4900 for running X.
After installing the card and rebooting, X will unfortunately no longer start. It just freezes completely, and cannot be killed with ^C or ^\, not can I switch to another VT with Ctrl+Alt+F*. The only way out is to press the power button and wait for the kernel to forcibly terminate X as a part of the shutdown procedure.
No amount of Googling has led me to a solution to this particular problem, and I've been unable to figure out what is causing this on my own, but here's what I've come up with so far:
- The kernel seems to recognize both cards (lspci: https://jon.tsp.io/share/firepro/lspci.log)
- The driver seems to recognize the chipset of both cards (Xorg: https://jon.tsp.io/share/firepro/Xorg.0.log)
- vgaarb is complaining about PCI devices not being VGA devices, but from what I've read, these messages may just be X probing for graphics devices (boot: https://jon.tsp.io/share/firepro/boot.log)
- X hangs when trying to open /dev/ati/card1 (strace: https://jon.tsp.io/share/firepro/Xorg.trace)
- When running catalyst-test, `aticonfig --lsa` says "No supported adapters detected"
- When running catalyst-firepro, `aticonfig --lsa` only lists the V4900
- Manually adding a Device section in xorg.conf for 6:0:0 makes no difference
I'm completely at a loss at how to fix this, so any and all help is very welcome!

Upon closer inspection, it appears the card may have been dead-on-arrival as not even the BIOS POST screen is visible when using only the W5000.
Will report back once I've gotten my hands on a new card.
