The trace dosn't look right, but you've probably hit
the con_flush_chars-called-from-interrupt problem.

Please add these two lines, let me know if it recurs.

oops in 2.4.2-ac20

2001-03-16 Thread John R Lenton 

What the subject says.

I copied the oops by hand, but the output of ksymoops doesn't
seem too totally wrong, so I guess I didn't botch it :)

I can't blame the box; I was about to Aiee myself, radeonfb is so
slow.
