I'm running a total of 20 Linux servers, most of them with 2.0.33.
One machine makes troubles, so I decided to try pre-2.0.34 from
uk.linux.org.
The machine still panics, the difference to 2.0.33 is, that I
get an Oops message (previousely the machine just hung).
Most of the machines have identical hardware, the difference here
is that this one has a Stallion EasyIO which serves currently
12 ISDN and 4 analog modems. I've been using the Stallion
Driver v5.3.3, and now version 5.4.0 from ftp.stallion.com but
I think the problem is not related to the Stallion driver.
Sorry if the information attached is not complete. If you need more
infos, please tell me; If anyone can tell me how to disassemble module
code, I'd disassemble ip_alias, too... Since this machine
is very critical I'd be glad to give you any help I can do.
Thanks
pm
