 I have OPEN-RD and SheevaPlug and testing both netbsd-6 and -current.

 NetBSD's in-tree gcc has some bugs for arm. Afrer announcing RC1, 
PR#46864 was fixed and pulled up to netbsd-6. Your system may be more 
stable if you use daily snapshot of netbsd-6 or next RC(RC2). At least,
my boxes are better than before.

 Another bug is PR#46898. This bug make a lot of problems... This bug 
is not fixed yet...
