Message-ID: <20050623135318.GC9768@suse.de> (raw)
Hi,
Something strange is going on with current git as of this morning (head
ee98689be1b054897ff17655008c3048fe88be94). On an old test box (dual p3
800MHz), using the same old config I always do on this box has very
broken interrupt handling:
[...]

idebus=xx

Going to UP makes it work just fine for me. Does anyone know what is
going on here?!
