It seems that this bug has been solved in the DRM module in CVS in November, see https://bugs.freedesktop.org/show_bug.cgi?id=4797 The problem is that the changes are not included in kernels 2.6.14 and 2.6.15 (released yesterday). I've asked on the DRI-devel mailinglist if a patch can be made available that can be included when building these kernels. If not, a workaround is to add the Option "OldDmaInit" "true" in the Device section of xorg.conf for the card as a workaround. My problems were solved by this setting for the card, an MGA G400 DH AGP. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
