--IrhDeMKUP4DT/M7F Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I have a Huawei E169 3G modem which I'm using with the u3g driver on -current/i386 from about 4 weeks ago on my Aspire One (dual-core N270). If I access the stats port (/dev/cuaD0.2) then the system will randomly hang. The problem seems to occur more frequently when I'm using X but I've also seen it (once) when I was using a VTY. I'm not using hald. There doesn't seem to be a problem if I don't access /dev/cuaD0.2. When the system hangs, the 3G modem hangs up (though this may be the keepalive timer expiring at the remote end) and there's no response to the keyboard (Ctrl-Alt-Del and Ctrl-Alt-Fn from X; Ctrl-Alt-Esc and Alt-Fn from VTY; CapsLock, NumLock in either mode). The kernel still responds to pings over ethernet and I can change brightness via the keyboard so SMM is still working. Has anyone else seen anything like this? Can anyone suggest a way to track this down? I can't get to DDB, there's no serial, firewire, PCcard or similar I/O. --=20 Peter Jeremy --IrhDeMKUP4DT/M7F Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iEYEARECAAYFAkomK6UACgkQ/opHv/APuIfvZACfRUs3Y2gv5CyMNdhxz0gqG7G2 a30An3QRSs/+ZQaazSEBCyW1WZoJUtcw =CR1N -----END PGP SIGNATURE----- --IrhDeMKUP4DT/M7F--
