How does VGA routing work on the PCI bus, what gets routed? Memory at A000 plus IO ports, just mem??? My top choice is still two enabled VGA devices. I suspect that X libvgahw is writing to the registers and both cards are seeing the writes. The bug has a very specific profile - a VT switch from X to console or vice versa triggers it. But it also has the unique characteristic that if you switch X to console to X things work ok. Same for console to X to console. It is easy to recreate you need one PCI and one AGP card. Run without framebuffer on the primary card. Reset the secondary card with a reset program (you can use X to reset it). Load fbdev on secondary. Start X. fbset from an xterm. System dies. This works for every combo of cards I own so it does not seem to be driver specific. --- James Simmons wrote: > Jon are you using a vanilla 2.6.6 kernel.

It might be a cons2fb mapping issue. ===== Jon Smirl jonsmirl@yahoo.com __________________________________ Do you Yahoo!?
