Summary: After suspend/resume, nwam doesn't refresh it's
interfaces.
Classification: Development
Product: nwam
Version: unspecified
Platform: ANY/Generic
OS/Version: All
Status: NEW
Status Whiteboard: nwam1-build:2009-04-29
Severity: major
Priority: P3
Component: ON daemon
AssignedTo: nwam-dev at opensolaris.org

After I suspend and resume my Toshiba r600 and MacBook Pro, nwamd doesn't
appear to do anything to refresh that state of the network, which results in
the machine being unable to connect to any network, wired or wireless.
The only solution appears to be to restart the nwam service, but when I tried
this it appeared to be locked with the stack-trace below.
It eventually was killed by SMF, and then I was able to enable it again. After
a while it eventually picked up a DHCP address - but it seemed to take a minute
or so after it had connected to the wireless network. [Could this be because
dhcpagent was after waiting a while for a response and had several retries with
increasing gaps?]
The stack of the lock was:
