The lock.hw_lock variable in the kernel that causes the infinite loop by being
reset is being reset upon screen closure called upon an xrandr operation. An
error message
"error setting MTRR (base = 0x20000000, size = 0x10000000, type = 1) Invalid
argument (22)"
is emitted by both kernel/dmesg and by libpciaccess. Following this, there is a
close, and in that close operation the flag is reset. The associated gdb log
illustrates this activity. The 3rd pci region has the failing base
address/size.
