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. -- Svante Signell [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?
