I have an SN10000EG rev.A1 which suffered the same problem when installing Lenny.
(System locks up, no response from keyboard, caps-lock and scroll-lock flashing. Booting with pci=noacpi or avoiding bringing up GbE prevent the problem.) I compiled[1] 2.6.30 and this problem went away. I haven't attempted to find out which commit fixed the problem but could be persuaded to investigate git-bisect if it's important. Kernel compile takes around an hour. The "eth0: excessive work at interrupt." still occurs if I flog netcat in both directions at once (~22MiB/sec). I hope this is useful, -- Matthew [1] This was "v2.6.30" from git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git plus Juerg Haefliger's c7temp patch at http://lists.lm-sensors.org/pipermail/lm-sensors/2008-June/023456.html (from which I've yet to see data), compiled with "make-kpkg --initrd ..." -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
