Subjectcrash in vesafb?
I installed 2.2.0pre9 with vesa framebuffer support enabled. If I boot with the
ypan/ywrap options, the machine crashes after some time. Actually, most of the
time it doesn't actually crash, it switches my monitor off, and the only way I
know to bring it back is reboot. A couple of times it actually froze solid. I
have an ATI Mach64 card (Xpert98). I haven't tried the Mach64 fb too much,
because it doesn't display properly (some pixels disappear etc). I have no
trouble if I use the vesa:redraw option instead. This generally happens after
some time, and often if I am scrolling screen-by-screen using less (say a man
page). Couple of times it also happened while in vi. There were no error
messages or OOPS, so can't help there.
