I have two ADSL lines with an ISP which supports multilink and two USB Speedtouch modems on one box.
Using the kernel driver I can connect to both lines separately and together fine. However, as soon as I add the 'multilink' option to PPP option file, it stops working; I get a modprobe and an ioctl(SIOCSIFMTU) error (see sys log below) when trying to connect the first line and ppp dies, regardless of which line I try first.

HOWEVER, if I switch to the user space driver, adding the multilink option works fine, I can connect both lines and PPP bonds them together as one without any problem. Can anyone even suggest how I might troubleshoot/find out what the kernel driver problem is, let alone fix it? There's nothing else in any of the logs to give any clues apart from above, even with the debug and kdebug 1 options. I'd like to use the kernel driver if poss. I have all the kernel PPP options compiled as modules, and without the multilink option ppp loads them all just fine, I don't know which module it is complaining about.
