[Antonio Olivares]

Dear fellow fedora users,

I had found a way to run this machine(the one that froze a great many times).  I used boot parameter acpi=off and it worked fine, except when I connected to internet.  I connected with an external usb modem and it worked for a while till it froze.

I have installed testing kernel 

[olivares at asus-amd64-athlon ~]$ uname -r
2.6.27.9-159.fc10.x86_64

and I booted without acpi=off and it worked for about 1 hour.  I was listening to music using mplayer and I pressed page up to play the next song and the machine froze.  Is there a way to get a traceback or a log that will determine the cause of the crash?

At the modem I am connecting with a borrowed external modem 
usb 6-2: configuration #1 chosen from 1 choice
usb 6-2: New USB device found, idVendor=0d08, idProduct=0300
usb 6-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0

Thanks,
