Anyone seen similar problems? Yep, its a patch I have here as: ppp_async-callable-from-hard-interrupt.patch that is prob in -mm as well (Andrew? - sorry, did not check). I cant remember where I got it, but I have had it around until yesterday when at parents and have to use ppp again (in hope of fixing some other issue that is prob the binary-only drivers problem :/). I am not sure if it may be interaction between Greg's latest tty patches (which I have in my 'tree' as well), or if it is just broken for some setups (usb modem with binary only driver over here) - I may try to test this theory tomorrow if somebody do not beat me to it.
