Probably, but I think I found the reason. Whenever I build the kernel
with "optimize for size" it hangs after an hour with intense net load
and io load (I made a loop that dd if=/dev/cdrom)
When I disabled "Configure standard kernel features (for small
systems)" (gcc -Os) the problem magically went away.
So I think its a bug in gcc version 3.4.4 (Gentoo Hardened 3.4.4-r1,
ssp-3.4.4-1.0, pie-8.7.8)
Makes me nervous because I have built everything with -Os.
I can probably just report it on bugzilla directly?
