--- Comment #184 from Mathijs Kwik bluescreen303@gmail.com 2010-09-29 02:09:45 CDT --- The one in maverick (2.6.35-*) does let you play wow. At least for me it turned out the bug was not this one reported here, but rather http://bugs.winehq.org/show_bug.cgi?id=24193
As a workaround I turn off (0) this new ubuntu security feature before WoW and switch it back on afterwards (1).
(as root) echo 0 > /proc/sys/kernel/yama/ptrace_scope
Disabling security features is not as bad as it sounds. Vanilla 2.6.35 does not contain it. Everything before 2.6.35 doesn't as well. So you will be "as secure as lucid" so to speak.
