Hello, I'm doing some work on tridentfb driver but encountered a weird problem.
When I compile custom kernel with tridentfb, it hangs with Blade3D card (ID 0x9880) in blade_image_blit(). The screen is blank with some artifacts and machine does not respond to ping or keyboard. However, it can be rebooted by Alt+SysRq+B. It works fine with other cards (3DImage 9750 and CyberBlade XP) with no blit implementation. Commenting out contents of blade_image_blit() function makes the hang go away (nothing useful on the screen, of course).
The weird thing is that the Blade3D card works fine when I load Debian kernels! Debian 3.16-0.bpo.3-686-pae works fine but when I compile 3.16 kernel, it hangs.
Any ideas?
