Re: Radeon 7500 w/ DRI locking on restart of X

Eric, I updated my 5.1-RELEASE system to CURRENT dated today at
approx. 9:10 CDT to give your changes a try.  I had a bit of a fright at
first with kernel panics right at the end of the boot sequence but it turned
out I had forgotten to disable the ltmdm code -- the kernel module
compiled under -RELEASE wasn't friendly to -CURRENT.

I've got just a basic install with my custom kernel.  I'm using the packages
for X from the 5.1-RELEASE cd running twm.  Hangs on restart are gone!
I restarted about 10 times in a row and ran glxinfo and glxgears each time
to verify DRI was still activated and working -- no issues.  VT switches are
fine (even while running glxgears).  The one thing that does not work is 
resume from acpiconf -s 4 (disk) -- there is a failure to refresh in X and no
ability *apparently* to switch to a VT; the keystrokes just generate beeps.
Interestingly, the cursor still changed between the different modes when 
mousing over the xterm and onto the background.  Also, Alt-Cntl-Del did
work just fine.

The only other thing I noticed is that there seems to be a syslog entry for
every instance of running glxgears that reads:

[MP SAFE] drm0

Is this expected behavior?  I noticed that same message (in brackets) in
front of each of my disks as they were probed during boot.

Any further info you'd like or more testing I could do to help?

                                                                                                  Sean

That patch has been in our XFree86 for quite a while.  For those of you
using -current, could you try with the latest DRM which I committed to
FreeBSD CVS a few minutes ago?
