The last line "POST: 0x00" repeats forever. PC80/keyboard.c is trying to initialize the keyboard. The code that is running is
/* empty input buffer or any other command/data will be lost*/
while ((inb(0x64) & 0x02)) post_code(0);The inb(0x64) reads 0xff forever. I heard that the keyboard initialization may not be needed.
How can I fix this? Thanks.
As was noted earlier on this list, that keyboard controller part is "seriously fucked up" on that board.
for now, turn off the keyboard, there's something wrong on that mobo we have not worked out.
Second, write user-mode linux programs to try to get that stupid part to work, and see what is wrong.

p.s. note I am back, but under really bizarre circumstances, as you can tell by the line at the end of this note.
