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. usbdevs -v: Controller /dev/usb0: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), VIA(0x0000), rev 1.00 port 1 powered port 2 addr 2: full speed, power 100 mA, config 1, Qualcomm CDMA Technologies MSM(0x3196), Qualcomm, Incorporated(0x05c6), rev 0.00 kgdb kernel.debug /var/crash/vmcore.0: [GDB will not be able to debug user-mode threads: /usr/lib/libthread_db.so: Undefined symbol "ps_pglobal_lookup"] GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
