Package: ppp
Version: 2.4.4rel-10
Severity: serious
Justification: Policy 1.1


pppd will cause keyboards to stop functioning if using a USB modem.

The problem happens *exactly* in this order:

1) Disconnect (kill pppd).
2) Wait for daemon to completely exit (watching syslog)
3) Once down, remove USB cable.
4) Keyboard no longer works.

Interestingly, even a USB keyboard will not work once this happens. I am 
running an IBM t23 thinkpad.
When this happens, the *ONLY* way to get back into the machine is restart. Also 
note, even if you plug
a USB keyboard in AFTER this has happened, you still cannot use it. I am not 
sure if this would be a Xorg
problem, there are no errors being written to Xorgs logs when this happens.

I DO get an interesting log entry - not sure if it is related or not:

-----LOG------
Dec 12 11:40:33 astro pppd[4587]: Connection terminated.                        
                // <- Hangup as normal
Dec 12 11:40:33 astro pppd[4587]: ioctl(TIOCSETD, N_TTY): Interrupted system 
call (line 571)    // <- Related?
Dec 12 11:40:46 astro kernel: [ 7234.328080] usb 2-1: USB disconnect, address 4 
                // <- Modem removed
-----END------

And thats it. Those are the last 3 log entries that are written. The USB 
disconnect is the USB modem
being removed.

The "USB modems" are also 3G Cell phones (one LG Fusic and another is a palm 
centro) - if that has anything to do with it.
