Issue #1, dhcpcd is handling a truncated lease. This usually means a
slightly RFC incompliant server fixed here:
http://roy.marples.name/projects/dhcpcd/info/3fd740f3ed17e902

Issue #2, dhcpcd is adding an incorrect netmask. Maybe fixed here, but
I've not tested your specific case yet:
http://roy.marples.name/projects/dhcpcd/info/025c74b42993bc3f

What is interesting is your claim dhcpcd is changing the default route,
but there's nothing in the logs you provided to actually prove that - no
mention of a default route is made.

Can you either test a trunk snapshot (ideal), or the two above patches
and see if they help any?

Thanks
