Found via topsite bughunter tests on an old windows 7 workstation with FX5500 card During startup Firefox trunk debug build crashes with: Assertion failure: [GFX1]: D3D11 device creation failed: 0x887a0004, at c:\builds\moz2_slave\m-cen-w32-d-000000000000000000\build\src\obj-firefox\dist\include\mozilla/gfx/Logging.h:513
David, this looks like it is related to device creation changes you made. Ideas?

Also, for reference: DXGI_ERROR_UNSUPPORTED = 0x887A0004
This assertion  was added in bug 1284672, so redirecting ni? at Matt. Probably the right answer here is to just remove the assert.  http://searchfox.org/mozilla-central/rev/c31ad35f39c6187b2e121aa6d3a39b7f67397010/gfx/thebes/DeviceManagerDx.cpp#285

I'm pretty sure the assertion was existing, but I agree that we should get rid of it. Failing to create a device (possibly because the system only supports d3d11 level 9.3?) shouldn't be a fatal assertion.
