Package: linux-image-2.6.16-1-powerpc Version: 2.6.16-10 Severity: normal My laptop (a PowerBook G4 15", with a Radeon 9600 video card) has been oopsing a fair bit lately, usually when my wife tries to use a second X server via xscreensaver's "New login" function. Unfortunately I can't be any more specific than that. I'm running current unstable across the board; in particular I have xserver-xorg 7.0.14 and xserver-xorg-video-ati 6.5.8.0-1, although this was also happening before the upgrade to modular X. Here's a recent backtrace:
