 Hi,
 
 I recently upgraded one of my Mac Mini G4 machines to 6.0_BETA,
 and even though I don't have console on the box, I'm pretty sure
 this bug has struck there as well.  The reason I say this is that
 I lost connectivity to the box for a few days, but after I
 rebooted it with power-off / power-on, I got messages from
 mailer-daemon about delayed or failed delivery of e-mail messages
 in the time it was "off-air".
 
 I'm going to patch the source tree with the workaround posted
 here earlier for the gem driver to see if this stabilizes its
 connectivity.  Another option could be to use the now-recognized
 bwi0 interface...
 
 So, I'm pretty sure this is a gem driver bug, and not something
 only seen on sparc64.  And... we really should fix or work around
 this problem before we release NetBSD 6.0 proper.
 
 Regards,
