Hi,
I'm using the Alcatel SpeedTouch modem. It is working fine. :-)
Meanwhile, when the pppd process is killed, the following oops appears.
It seems ppp_synctty is trying to enable softirqs while softirqs are
already enable.

The problem is that do_tty_hangup() in tty_io.h calls the
write wakeup callback with disabled interrupts. The
notes in this function question the validity of disabling
interrupts at that point. I'm not familiar enough with the
locking issues for this function to comment.
At some point ppp_synctty.c was changed to use
spin_lock_bh and spin_unlock_bh in the write wakeup callback.
These macros complain when called with interrupts disabled.
Perhaps changing ppp_synctty.c to use spin_lock_irqsave
and spin_lock_irqrestore is the best fix.

My 2 cents would be to keep it as it is. BK says WARN_ON was used
in place of BUG_ON in local_bh_enable just for the the ppp ldisc.
We all know tty locking is broken and needs rewrite, but
if we kill such symptoms at driver level, it'll probably deprive
some data points to whoever rewrites the tty layer.
Thanks,
Kiran
