[Pkg-fglrx-devel] Hung PC with black screen and white cursor on boot or gdm3 start

Hi fglrx package developers,

     I've been unsuccessful at getting fglrx-driver (1:14.9+ga14.201-2) 
working on debian jessie for a few days now. When the driver is 
installed and loaded in the kernel and I start gdm3 I get hung pc 
shwoing a black screen with a white cursor in the left corner. I cannot 
login with ssh or get shell with ctrl-alt f1. Even worse, the hang 
leaves no logs in systemlog, Xorg.0.log, kern.log and messages. I've 
confirmed this by deleting those files and starting gdm which hangs the 
system, then rebooting into gdm which produces the same hang, and 
finally checking the logs by hard rebooting into rescue mode. After all 
this the logs are still not recreated.

     However, I am pretty sure the driver is being loaded into the 
kernel. If I delete the xorg.conf file generated by aticonfig --initial 
-f, X doesn't load the right driver but will boot to the gnome frown 
face and I can get into a shell though ctlr-alt f1. In kern.log I see

fglrx 14.20.7 [Sep  2 2014] with 1 minors

     I've uninstalled fglrx and tried installing the latest upstream 
version, AMD Catalyst Omega 14.12 
<http://support.amd.com/en-us/download/desktop?os=Linux+x86#>, and got 
the same hung pc with white cursor. This makes me think this problem is 
a upstream issue. I also noticed the latest version of the install does 
not support building packages for Debian.

     Other things tried:
     I've tried rebuilding the fglrx-driver from source and got the same 
hung pc.
     I've tried rebuilding Xorg-server from source so that Xorg is built 
with the same kernel headers as the driver got same hung pc.    .
     I've tried add 'nomodeset' to the kernel boot options and got same 
result.

     System Information:
     Chip: AMD A10-7850k Kaveri on Gigabyte GA-F2A88XM-D3H (AMD A88X 
[Bolton D4] Chipset)

     $uname -r : 3.16.0-4-amd64

     $Xorg -version

     Current Operating System: Linux plazmon 3.16.0-4-amd64 #1 SMP

     Kernel command line: BOOT_IMAGE=/boot/vmlinuz-3.16.0-4-amd64

     xorg-server 2:1.16.2.901-1 (http://www.debian.org/support)
     Current version of pixman: 0.32.6


     This bug seems to be different from #765109 since I'm getting a 
total hung pc with no logs. Please let me know if I should open this 
with a bug report or if there is anything else I should try.

     Thanks,

     Greg
