Now, consider the same bankruptcy scenario. Assume that from day-1
the code has been simultaneously GPL and proprietary, identical
codebase. Does this change anything? If not , what could be put into
the license that would solve the problem? -steve

perfect case in point: the recent X licensing fiasco. TOG announced that
the next version of X they released would be under a much more commercial
friendly, and much less open source, license. within days, hundreds of
developers, led primarily by the XFree86 people, and with vocal support
from such free software leaders, were ready to fork off from X11R6.3, and
leave TOG in the dust. realizing they were about to slit their throat, TOG
backed off and canceled the license change.

Thanks for the warning I was actually going to install Kernel 2.2 on my
machine at home tonight. My CPU is a cyrix 120+. But I'll have to look
in to it a bit further as I can't afford to have my computer in a state
of limbo at the moment!

Does this mean that the same interrupt could be serviced by two
different CPUs at the same time (when the first CPU is not yet
finished with it´s interrupt handler while the same interrupt happens
again)?

One at a time in the sense "one bottomhalf will never be executed by
more than one CPU at the same moment" or in the sense of "there is
always only one bottomhalf active, not even two different bottom
halves on two different CPU´s"?
To summarize the critical situation I think I know about (scenario:
driver which registered one interrupt and uses several bottom halves):
(- interrupt could be running on more than one CPU at once?)
- bottom half could be interrupted by an interrupt
(- bottom half could be running on more than one CPU at once?)
- syscalls could be interrupted by interrupts
- syscalls could be interrupted by bottom halves
- syscalls could be running on more than one CPU at once
Anything I forgot?

GNU ld (or, more precisely, libbfd, the binary file descriptor library

others.

I suppose you could check the file(1) utility under Unix or Linux. The
file /etc/magic or /usr/share/misc/magic gives magic numbers for any
number of file formats, including (in the version distributed with
Debian Linux, at least) pretty much all known executable file format
magic numbers on any Unix dating back to before the French Revolution.
The format of the magic file is not hard to read; read the manual page
for details. My magic file greps in at 49 lines with "COFF" in them.

Well, I have both freedos and dosemu installed. I suppose xdos always

Why me??? The problem started when I installed an updated RPM for
modutils, and then it just went downhill from there. Now my machine
is a mess, and currently running Solaris until I can figure out
a clean way to do this. I did have 2.0.36-3 running well in SMP
except for one *very* annoying thing -- no matter what I tried
(everything from RTC, xntpd, running ntpdate and rdate via cron,
etc) the time drift was simply too far out to be usable. This is
supposedly known problem with 2.0.x series, so I was hoping 2.2.0
will fix it.
Can you load modules using insmod w/out any trouble? If so, I'm
going to start from scratch yet again and try that.
Regards,
Mumit

Hello all,
I've got this particularly annoying problem when SSHing out
through my 2.0.36 box w/ IP Masquerading. If I'm sitting behind the box
and connecting to an outside server, the SSH connection eventually goes
away. This only happens when I am idle for a period of time.
I'm running SSH 1.2.26-1us from ftp.replay.com.
Any suggestions? It's a minor annoyance right now, but enough to piss me
off every couple of hours.

I configured a modular kernel typed:
make dep; make clean; make zImage; make modules
make modules_install
make install
added vmlinuz-2.2.0-pre6 to lilo.conf
rebooted, worked fine.
RedHat has the latest modutils. Seriously, it just worked.
If you want, e-mail me and I'll send you my kernel configuration file.

I have got is sorted out. Bian Wheeler's response is absolutely correct.
emacs is now working fine but for it to do so you have to take the "apply
styles to non KDE applications" off and execute "xrdb ~/.Xdefaults".
I tried using the SVGA server and (becasue this is posted everywhere) I
didn't bother changing my run level from 5 to 3.... guess what happened? The
driver didn't work and I had to recover the system with a rescue disk! I
think that the resolution was too high.
Anyway I am back to using the S3 server which still presents small problems
but they disappear when I load GIMP!?! When I have more time I'll look into
this problem in more depth!
