Thanks. I tried the enable_mtrr_cleanup line earlier and added the mtrr_spare_reg_nr=0 later (in menu.lst), it didn't make the driver work.
After reading this: http://lists.opensuse.org/radeonhd/2009-05/msg00070.html and this: https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.24/+bug/224404/comments/42 ,I tried compiling a custom kernel with options "CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=1" and "CONFIG_MTRR_SANITIZER_SPARE_REG_NR_DEFAULT=0". This made no difference. I didn't notice any changes in Xorg.0.log besides the added line: "(II) RADEONHD(0): Current Engine Clock: 13823570", which (i assume) just came from using the most recent (20090519) driver from your PPA. I'm aware that this is not a radeonhd issue, so i'll keep checking bug 341681 here on launchpad, and bug 20645 on bugs.freedesktop.org. This post is intended to describe some things that didn't work. some (perhaps) relevant output below: ------------------------------- $ grep "CONFIG_MTRR" /boot/config* /boot/config-2.6.28-12-generic:CONFIG_MTRR=y /boot/config-2.6.28-12-generic:CONFIG_MTRR_SANITIZER=y /boot/config-2.6.28-12-generic:CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=0 /boot/config-2.6.28-12-generic:CONFIG_MTRR_SANITIZER_SPARE_REG_NR_DEFAULT=1 /boot/config-2.6.28.9:CONFIG_MTRR=y /boot/config-2.6.28.9:CONFIG_MTRR_SANITIZER=y /boot/config-2.6.28.9:CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=1 /boot/config-2.6.28.9:CONFIG_MTRR_SANITIZER_SPARE_REG_NR_DEFAULT=0 $ cat /proc/mtrr reg00: base=0x000000000 ( 0MB), size= 2048MB, count=1: write-back reg01: base=0x080000000 ( 2048MB), size= 1024MB, count=1: write-back reg02: base=0x100000000 ( 4096MB), size= 1024MB, count=1: write-back $ ./mtrr-uncover Initial MTRR configuration: 0 0x000000000-0x07fffffff write-back 1 0x080000000-0x0bfffffff write-back 2 0x100000000-0x13fffffff write-back No changes made. ** Attachment added: "dmesg" http://launchpadlibrarian.net/27057528/dmesg -- [HD3650] fails with mobility hd3650 on startup if > 2GB RAM https://bugs.launchpad.net/bugs/352050 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-radeonhd in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
