>Description:
Laptop Gateway Solo 9500
OS pulled in for date=2004.04.24.00.00.00 stops working
OS pulled in for date=2004.04.23.00.00.00 stops works

Missing fxp

When looking for changes on this date I could not find anything.
Apparently I don't know what to look for.

The rest of the dmesgs were the same(if you want the complete dmesg
let me know.
