>Description:
Netbooting netbsd macppc current (6.99.23)results in an unreadable console 
output. ssh access is not feasible. Console output is like: "blurred text 
-mixed pixels which they seem like words- scrolling upward to the screen". The 
output is unreadable.
I have also used kernel 6.99.15 -this one resides on the disk of the laptop and 
i copied it on the netboot server- but the console output on the laptop is the 
same when this kernel is used for netbooting.
Laptop is G4 aluminum case 1.33.
>How-To-Repeat:
Netboot macppc using current kernel and userland (6.99.23)
