This patch has fixed the kernel hangs I had been having on a system using three instances of pppd a USB HSDPA modem. In the situations where the hang would normally occur, what I now see is disconnection and reconnection of the USB device, apparently triggered by electrical noise or RF interference. I presume that what was happening before this patch was that the disconnection of the USB device caused a deadlock, associated with this area of ppp_async. -- James Cameron http://quozl.netrek.org/ HP Open Source, Volunteer http://opensource.hp.com/ PPTP Client Project, Release Engineer http://pptpclient.sourceforge.net/ - To unsubscribe from this list: send the line "unsubscribe linux-ppp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
