Ken, We are aware of the problem, per below. The bypass is to shut downthe modem and unload slamr , then restart. If you are using the sl-modem-daemon scripts, just$ sudo /etc/init.d/sl-modem-daemon restart If notCtrl-C to kill slmodemd$ sudo modprobe -r slamrunloading the driver. Reload$ sudo modprobe slamrand restart$ sudo slmodemd -c USA /dev/slamr0 MarvS from Gustavo Fernando Padovan <gfpadovan@xxxxxxxxx>to discuss@xxxxxxxxxxxxxxxxx Fri, May 30, 2008 at 11:26 AMsubject modem on kernel >=2.6.24 hide details May 30 (7 days ago) Reply Hello, I'm testing a modem motorola 1057:3052 with kernel >=2.6.24 and I hada problem, the modem connects just once, in the second try the modemdoesn't respond and I need to unload the slamr module and load itagain.
