Now before 2.6.0-test7-bk1 (that means up to 2.6.0-test6) I had this error
message popping in my syslog file (and tty) whenever there was data
transmission over my ppp (pppd 2.4.1) dial-up connection (resulting in a
very big /var/log/syslog file around 20 mb! and a very slow connection and a
very unresponsive system)(I had no problems at all on 2.4.22-ac4) :

That "badness" is that the TTY code is calling local_bh_enable()
in an IRQ handler context ... which it shouldn't be doing.
