My kernel configuration
I'm using jglisse kernel:
git://people.freedesktop.org/~glisse/drm-next drm-next-radeon
52c34724734132e7d416ce5ab5e934d702e8f179.
For now I have tested only KMS setup.
libdrm branch: modesetting-gem 1edb70f1b909d06f1c0ee7c9c794aec99454e488.
Bug is reproducible even without X running.
Running 32bit version of drmstat:
drmstat -v -O /dev/dri/card0:
Produces this kernel error:
[ 2446.945430] ioctl32(lt-drmstat:14975): Unknown cmd fd(3)
cmd(c0246400){t:'d';sz:36} arg(08213008) on /dev/dri/card0
[ 2446.945458] ioctl32(lt-drmstat:14975): Unknown cmd fd(3)

[ 2446.945464] ioctl32(lt-drmstat:14975): Unknown cmd fd(3)
cmd(c0086401){t:'d';sz:8} arg(fffab5ec) on /dev/dri/card0
Starting 32bit glxinfo:
libGL: OpenDriver: trying /emul/ia32-linux/usr/lib/dri/r300_dri.so
libGL error: failed to get magic
with kernel error:
[ 2694.804332] ioctl32(glxinfo:15042): Unknown cmd fd(4)
cmd(80046402){t:'d';sz:4} arg(ff938800) on /dev/dri/card0
I hope this is only error in my kernel configuration.
