           Summary: Gallium R300g can crash PC when running celestia.
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.sourceforge.net
        ReportedBy: rankincj@googlemail.com


I tried running celestia 1.5.1 using the R300g driver from git, vanilla Linux
2.6.33.1 and libdrm 2.4.18, but celestia hung. In one case, the entire PC then
locked up shortly afterwards. However, in one case it recovered and recorded
these messages in dmesg instead:

This is with a Radeon 9550 (RV350).

38c7a01b6c220ad04c5754602673ad3cf36ad508 should fix the hardlock, although it
renders Earth incorrectly. b6df7aed60189d5f28a139c6fe351022ca2907a4 keeps it
from crashing with a bad vertex program.

Closing for now; the incorrect rendering will get fixed at a later date.

It is no longer locking my PC up either :-). If the "incorrect rendering" that
you're talking about is the "blank" dayside of the Earth then in my case this
was due to celestia now using the OpenGL 2.0 render path with Gallium.
Switching back to the OpenGL vertex program render path (Ctrl-V) fixed things.
Celestia was still a lot slower under Gallium than classic Mesa, though.
