Hi,
as Justin just wrote, the core team can only fix bugs it knows about, so:
I experience 2 types of total system hangs under 2.0.5-Release,
1) in an xterm, while scrolling, the system sometimes and totally
unreproducable just hangs. This seems to occur more often the smaller
the used font and/or the larger the xterm is, or better the more
amount to scroll.
This also happened from time to time under 1.1.5.1 and was one of the
reasons i wanted to upgrade.
When this happens, the machine is totally frozen so there is not even
a chance to look from another side into the machine.
2) Disk i/o hangs, sometimes with the access LED on the controller on, some-
times off. The machine is operational as long as one does not "touch"
the disks, so i would be able to search for something if someone would
tell me where to search and what to search for.
3) lpt0 is sometimes not found, sometimes it is found during probe. It was
always found under 1.1.5.1.
The machine is a 486DX2 EISA machine manufactured by Kyocera:
