2.2.0: performance & isdn.

Post #1 of 4 (326 views)

Howdy,
I've just tried to install 2.2.0-pre9 (unpatched). Here's a little
report ...
1) I have an AMD K6, Stepping B (yes, the bad one) processor. 2.2.0
compared to 2.1.132 gives more sig11 errors, suggesting that the memory
handling routines has changed. Which, in turn, made me unable to do
some 'serious' testing.
2) A 'ls -l' in a directory containing a few files takes quite some
time. It lists say 5 files, then wait a couple of seconds, then list
the rest. 'tar' shows the same behaviour.
3) Isdn is _broken_. It was broken back in 2.2.0-pre1, but I had hoped
that it was fixed. For some reason, I can connect _once_. Further
connections succeed, but no IP-traffic is routed. What is the proper
way to upgrade the ISDN so that it works with 2.2.0? (I've downloaded
isdn4k-utils-3.0beta1 - but it doesn't give me any kernel changes!)
... I'm stepping back to 2.1.132 for a while ;o)
Kind regards,
Brian

isdn4k-utils-3.0beta1's ipppd (Or ANY ipppd) needs a short patch to
allow for the extra-version in 2.2.0-pre?. It chokes on the pre?, and
defaults to 2.0.x. Look into sys-linux.c in the ipppd source and comment
out the following code in the decode_version function:
if (*buf != '\0')
{
*version =
*modification =
*patch = 0;
}
This will allow you to dial in. This is NOT a problem with the kernel ISDN
code, but a buggy version decoding.
(I'm currently using an unpatched 2.2.0-pre9 with a modified isdn4k-utils
to dial in, so it definately does work)

Brian,
the appropriate way to do is:
go to
ftp://ftp.gwdg.de/pub/linux/suse/ftp.suse.com/isdn4linux/v2.1/
get
isdn -> isdn-9901201200.tar.gz
get
isdn4k-utils -> isdn4k-utils-9901211200.tar.gz
unpack it in /usr/src
mkdir /usr/src/linux/drivers/isdn/diehl
mkdir /usr/src/linux/drivers/isdn/eicon
in /usr/src/isdn: ./std2kern -d
then make config in /usr/src/linux und bake the kernel as usual
in /usr/src/isdn4k-utils:
make config && make && make install
don't forget to set the dialmode in your init script:
e.g.
isdnctrl dialmode ippp0 auto
and restart your machine.
Good luck.
Regards,
Gerry

Get the latest and greatest drivers via CVS and run './std2kern -d' in
the isdn directory.
The FAQ that comes with isdn4k-utils explains how to check out the
driver (and the utils, which are also available via CVS).
