PPP ooopses on 2.6.0-mm1

Hi all,

Here is what I get from syslog :

This somehow freezes X too. Anyone seen similar problems?

Hmmm, I have just had two nasty problems with X the last two days. The
first went unnoticed in the logs, but yesterday I got the following in
the logs. It seems strange to me to get an oops with mixed information
from XFree86 al PPP support.

*BIG FAT WARNING*, VMware modules were loaded, so take the following with a
BIG grain of salt:

Kernel version is 2.6.0, XFree86 is 4.2.1-9 and libc 2.3.2.ds1-10, all from
Debian Sid, not updated too frequently, to say the truth :)

Hope it helps.

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.
