I have found the same delay of the "hwinfo --monitor" output in 11.2 . But X is
running fine in 11.2. Top shows 100% cpu for hwinfo waiting for the monitor
info.

in 11.2
=======
strace shows the hwinfo is repeatedly waiting for iopl(0x3)

mmap(NULL, 200003584, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x7fe883eb8000
brk(0x8ca000) = 0x8ca000
brk(0x90a000) = 0x90a000
iopl(0x3) = 0
iopl(0) = 0
munmap(0x7fe883eb8000, 200003584) = 0
brk(0x82e000) = 0x82e000
brk(0x850000) = 0x850000
brk(0x872000) = 0x872000
mmap(NULL, 200003584, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =

brk(0x8ca000) = 0x8ca000
brk(0x90a000) = 0x90a000
iopl(0x3) = 0

in 11.3 MS6
