I try to cherry-pick the bit 17 swizzling patch, it looks like a proper solution for this issue, but lots of conflict when I merge to current Jaunty tree, I check for the upstream and find out that I need to pull lots of commit to solve the conflict. It is against the policy of SRU.
Fortunately we have the disable-gem patch which will force intel driver in the traditional mode and have some improvement with the benchmark. I merge the patch and build the kernel image. I put those packages at http://people.ubuntu.com/~ikepanhc/lp349992/ If anyone suffers with this issue, could you have a test with the http://people.ubuntu.com/~ikepanhc/lp349992/linux-image-2.6.28-13-ikepanhc-lp349992_1_i386.deb, and add the following line to "/etc/modprobe.d/options" options i915 enable_gem=0 Please let me know if it works fine or not. -- [i945 tiling] (Needs kernel 2.6.30-rc3) Low performance due to no A17 workaround https://bugs.launchpad.net/bugs/349992 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
