I've been trying to reproduce this bug with xserver-xorg-video-savage/1:2.3.0-1 libc6/2.9-25 xserver-xorg-core/2:1.6.3.901-1 I kept /usr/lib/xscreensaver/atunnel running for quite a while, without any lockup at all. I tested atunnel both in a standalone window (started as /usr/lib/xscreensaver/atunnel from a terminal) and in the xscreensaver-demo preview mode. It seems that atunnel is no longer able to freeze my system. Nonetheless, the test was not completely error free. Indeed, some worrying entries were logged to /var/log/kern.log: [ 582.975686] Xorg:5396 conflicting memory types 90000000-95000000 uncached-minus<->write-combining [ 582.975700] reserve_memtype failed 0x90000000-0x95000000, track uncached-minus, req uncached-minus [ 643.989097] atunnel:5735 conflicting memory types 90000000-95000000 uncached-minus<->write-combining [ 643.989123] reserve_memtype failed 0x90000000-0x95000000, track uncached-minus, req uncached-minus [ 653.768420] atunnel:5737 conflicting memory types 90000000-95000000 uncached-minus<->write-combining [ 653.768446] reserve_memtype failed 0x90000000-0x95000000, track uncached-minus, req uncached-minus [ 686.813969] atunnel:5756 conflicting memory types 90000000-95000000 uncached-minus<->write-combining [ 686.813997] reserve_memtype failed 0x90000000-0x95000000, track uncached-minus, req uncached-minus As a consequence, I am *not* sure that the bug can be safely considered as fixed... -- New location for my website!
