I run Ubuntu 9.04 on x86_64 on a HP Pavilion tx1219us laptop, with a nVidia MCP51 audio controller and a Motorola Si2054 modem codec. sl-modem-daemon fails miserably when dialing, both the version shipped with Ubuntu and slmodem-2.9.11-2009022. Here's what slmodem-2.9.11-2009022 does: <060.039566> main: startup write: 384... <060.040027> main: alsa xrun: try to recover... <060.071382> main: alsa xrun: recovered. <060.071759> main: dev read = 0 <060.072007> main: alsa xrun: try to recover... <060.103393> main: alsa xrun: recovered. <060.103766> main: dev read = 0 <180.151758> hw:0,6: modem_tty_write: hangup... <180.152905> hw:0,6: modem_hup...
