FreeBSD cdmarouter.internet.free 5.3-STABLE FreeBSD 5.3-STABLE #3: Thu Jan 13 00:47:29 CET 2005 root@cdmarouter.internet.free:/usr/obj/usr/src/sys/CDMAROUTER i386
>Description:
I have a big problem with usb modem GTRAN CDMA evdo 1x on FreeBSD 5.3-STABLE/5.3-RELEASE (updated 10. Jan 2005).
I use userland ppp to dial cdma connection and modem is connected to USB 1.1.
When I download data from Internet via this connection, so kernel often (several times every day) generate core dump.
It's usually when my connection work at high pressure.
