Comment 3 Adam Jackson 2016-10-25 15:53:36 UTC

The initial report here is a bit unclear. The real bug is that 6.9.4 assumed the existence of an X server API called xf86LinearVidMem, which only did anything meaningful on some _very_ old alpha CPUs. 6.8's xserver update eliminated that interface, but mach64 6.9.4-10 would still try to call it (and crash).

The initial report's text of:

Unsatisfied dependencies for xorg-x11-drv-mach64-6.9.4-9.el6.x86_64:
	xserver-abi(videodrv-15) >= 0 is needed by xorg-x11-drv-mach64-6.9.4-9.el6.x86_64

Is from attempting to downgrade from 6.9.4-10 to -9; since -9 was built against the older xserver ABI, the rpm dependency checks would refuse to allow it to be installed, since that _also_ would not work.

The upstream 6.9.5 release is entirely minor bugfixes relative to 6.9.4, including the one that fixes this issue:
