Andrea,
I've been running your changes on 2.2.6 for the last hour or so w/o any lockups. It nice to finally have a stable 2.2.x box, now if I could only figure out what changed between 2.2.5 & 2.2.6 linux1a-2.2.5#logname vanl linux1a-2.2.6#logname logname: no login name

here is /var/log/kernel... one interesting item i've not seen before is the Infinite loop message, so far it's only happened once and eth0 continued to function normally.
