Hi, i'm using mach64 drm driver from git (not in kernel source) git://anongit.freedesktop.org/git/mesa/drm on an old sony vaio pcg-fx80. My debian testing run fine until kernel 2.6.28.7 Start using new 2.6.29 kernel (tryied also .1 and .2) drm doesn't work. modprobing the driver get no problem. From syslog: kernel: [drm] Initialized drm 1.1.0 20060810 kernel: [drm] Initialized mach64 2.0.0 20060718 on minor 0 kernel: [drm] Used old pci detect: framebuffer loaded But, starting X kernel: mtrr: no MTRR for e9000000,800000 found ... .... [drm:mach64_do_dma_init] *ERROR* can not ioremap virtual address for descriptor ring ok... mtrr was wrong, correct this... echo "disable=1" |> /proc/mtrr echo "base=0x0e9000000 size= .... ... ...... the problem of mtrr is solved, but the 'ioremap' persist. Booting with nopat option 'solve' this but KDE freeze before login and nothing work again. Ask for any other info. thanks

Hope this help.
Hi, Freedesktop's Bugzilla instance is EOLed and open bugs are about to be migrated to http://gitlab.freedesktop.org. To avoid migrating out of date bugs, I am now closing all the bugs that did not see any activity in the past year. If the issue is still happening, please create a new bug in the relevant project at https://gitlab.freedesktop.org/drm (use misc by default). Sorry about the noise!
