[Pkg-virtualbox-devel] Bug#500484: virtualbox-ose: upstream Bug #1775, spammy PATM messages (aka huge logfiles)

[Stefan Lippers-Hollmann]

Package: virtualbox-ose
Version: 1.6.2-dfsg-6
Severity: normal
Tags: patch

Virtualbox upstream bug #1775[1] is also present in Debian's virtualbox-ose
versions in lenny (1.6.2-dfsg-6) and sid (1.6.6-dfsg-1) and manifests 
itself in repeating the following message numerous times in 
~/.VirtualBox/Machines/sidux/Logs/VBox.log:

00:00:30.075 PATM: Disabling IDT e patch handler c0344888

This blows up the log file significantly (up to several 100 MB) and has 
also significant negative side effects on the system performance of my 
Athlon XP-2000+.

Upstream, svn commits 12524, 12525, 12527, 12532, 12534 deal with this 
issue by rate limiting the PATM messages to 255 repititions (the commits 
above partly revert each other again, to keep the ABI for saved snapshots 
compatible). The attached patch, based on the aforementioned upstream 
commits, applies against virtualbox-ose 1.6.2-dfsg-6 and 1.6.6-dfsg-1 and
fixes the problem for me.
