Hi,

in recent current I get the following when I try to boot my Alpha:

Entering netbsd at 0xfffffxxxxxxxx
panic: tga_console (13, 0): couldn't map memory space


It seems the following change in sys/dev/pci/tga.c is the reason:

-----------------


If I revert to v1.15, the boot stops with

panic:tga memory not cacheable


I "fixed" this by removing the cacheable check and now it
works again, but I'm afraid that this is not the correct solution.
