I have been running 2.0.22 happily for some time on my dual P5-166
machine. Upon patching up to 24 or 25, I get complete system hangs
within an hour or two. No disk activity, nothing in the logs, frozen
video and keyboard. I haven't heard of anyone else having this
problem? Is this due to the new IRQ forwarding code?

This is a mixed IDE/SCSI machine with NE2000, soundblaster, IDE CD,
etc. Would be happy to provide any extra information.
