Description macro 2015-09-06 10:33:33 UTC

The following GPU lockup occurs consistently soon after starting Dillo (an fltk-based lightweight web browser) compiled without Cairo support.

I am happy to provide any additional information or diagnose further as directed.

"ATI Radeon 7500 QW (AGP/PCI)" (ChipID = 0x5157)

Kernel arguments:

radeon.no_wb=1
radeon.dynclks=0
radeon.agpmode=-1
radeon.gartsize=32
radeon.msi=0
radeon.dpm=0
radeon.aspm=0

radeon.bapm=0

One or more (not sure exactly which) are required in order for X to start without hanging the machine.
