I'd previously (accidently) noticed that unplugging the e169 whilst it was in use would hang my system. Upgrading to a more recent -current has fixed the problem - the e169 no longer randomly detaches and if I accidently pull the e169 out whilst it is in use, the system no longer hangs. >Can anyone suggest a way to track this down?

My solution was to enable watchdog(4) - which gave me a panic & crashdump. --=20 Peter Jeremy --n8g4imXOkfNTN/H1 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (FreeBSD) iEYEARECAAYFAkpFQD4ACgkQ/opHv/APuIfnoACgjbJCVrEQjQXIHXr8ZCtUqF8m U2QAnjE2dxYTjFFgf1AtVWnrHTI55Ih8 =YwKS -----END PGP SIGNATURE----- --n8g4imXOkfNTN/H1--
