booting screwed: ttyS0: LSR safty check enganged

[Uwe Brauer <oub@mat.ucm.es>]

Hello


After the latest 
apt-get upgrade
on my R40e IBM, booting has considerably slowed down,
in the boot process
for almost 5 min the screen is filled with messages:
ttyS0: LSR safty check enganged
I tried the kernel shipped with Knoppix 3.3 and different 2.24 kernel
which I compiled myself.

I also did 
./MAKEDEV console 
in /dev

No improvement.

Can anybody help me please?

Thanks
