Bug#455465: xresprobe: 100% cpu near thunk.c:92 x_outb
Package: xresprobe
Version: 0.4.23debian1
Severity: normal
When I run ddcprobe, it'll hang after 1600x1200x256 for minutes on end
using 100%cpu time. I've included a backtrace after interrupting it
there. I rebuilt xresprobe from debian sources, and added the -ggdb
flags for gcc in the ddcprobe/Makefile for debugging.
Presently I have a pci card installed (oem: line) in favor of the
onboard card. I was going to see if a different pci video card would
work around #442771.
Thanks!
