Hi!
The problem first appeared to me while I was compiling the ac21 kernel
running with 2.4.0-test1-ac20. I couldn't track down the EIP that time,
because for building the ac21 I cleaned my /usr/src/linux. I think I
was chatting on the IRC and listing to music with mpg123.
Here will just paste the dump. I mailed it to the parallel port people,
the told me that it hasn't to do anything with the parallel port and
I should try to reconstruct the kernel and track down the EIP, because
I offered it.
My screen is flooded with "parport0: Timed out"

Today the problem occured to my again. I'm running the 2.4.0-test2-pre10
kernel right now. I was using mpg123, BitchX, setiathome, the debian
updater and xdm with XFree86, and some other usual stuff running like
fetchmail, exim, etc. I got 2 dumps, but I was just able to chatch the
second one and a little part of the first one. (I cutted the BitchX
output that was inbetween.)

If you want some more information please tell me. I will keep this
this kernel and compile the new 2.4.0-test2. I get the kernel-digest,
but it would be friendly if you could CC the mails about this issue
directly to me.
TIA
