The failure I had with softupdates when using 2.0BETA until last days of se=
ptember was very unusual and singular.
After a lot of disk activity, like buildlinking some package and untarring =
some source, both activities done at the same time, the system did not resp=
ond and the disk keept working, in an intermitent but noticeable way.

But now, the tasks I was doing were different. I was compiling a package, a=
nd creating some image from a cd. There was a lot of disk activity, the ima=
ge was created with maxim speed and the system hanged, the mouse pointer st=
ill moved but the keyboard was dead, and the disk keept working.

How can I get a good backtrace of this problem?

thanks.
