Hi,
I just got a new notebook with an internal Rockwell PCI modem (I think
the vendor id is 127A, device id is 1005).
I think it can't be activated in linux 2.2.10. Or did I miss
something? Can I help to implement support for this piece of hardware?
thanks.

CUPS - Never heard of it, but printing under linux is almost purely
userspace. Most linux distros seem to ship with the BSD printspooler,
but SYSV and probably some others are available. The kernel contains
the port drivers, but the actual spooling is userspace. provided this
can be provided in userspace I suspect that someone somewhere will
write a daemon to handle it, when it becomes an issue for them, but at
the moment most people use BSD.
UDI - The V1.00 spec has just been released, but it seems (from reading
the kernel list), that most of the people who really know this stuff
think that it leaves too much undefined, and that there will be serious
proformance issues. I doubt that it will make a mainstream kernel any
time soon.
If UDI takes off in a big way, then I dont doubt that support will be
written, but until it becomes an issue I dont think that anyone is
likely to do much work on it.
I might be pleasantly surprised, but my betting is that it will be
really hard to integrate this cleanly, and I very much doubt that
linus will allow something that doesnt integrate cleanly into 2.3 at
this late stage.
USB and Firewire are much bigger problems at this point. Actually the
really thorny problem is support for generic hot pluggable devices,
as there are serious device naming issues.
Disclaimer: This is just my reading of the situation.

Not much of an answer, I'm afraid, but I've had this same card working just
fine under 2.0.36 (Debian system, but the kernel was built from the regular
issue source tree). I've always loaded the driver as a module just because
I routinely make most anything that doesn't need to be embedded a module.
The only difference I can see is that I've never specified the 3rd or 4th
parameter, just the io and irq values.
General troubleshooting stuff: remove everything you can from the system,
try different bus slots, try the card in a differnt machine if you can, etc.
If you've had the card out of service for a while, check that it's working
with one of the other OSes if you can; hardware failures can be sudden and
unheralded. Etc. Given the error reported, I'd look especially hard for
anythign that might be trying to use the same IRQ. If the machine has any
form of PnP or PCI BIOS make sure that IRQ is flagged as reserved for legacy
ISA use. And so forth.
Luck!

you didn't specify enabled languages in the configure statement. you
get c anyways. the other i believe must be requested.
ripped from my gcc-2.95.1.spec file (an rpm thing)
../configure --prefix=/usr \
--enable-shared --enable-threads \
--enable-languages=c++,f77,objc \
$RPM_ARCH-redhat-linux
also gcc will try to put includes in g++-3 rather than g++.
although news is probably best, feel free to ask me by mail too. i've
set follow-ups to comp.os.linux.development.system. not that it is
the best but i read it and that will reduce usenet clutter.
hope this helps.

The approach that I suggested above amounts, essentially, to creating
a virus that treats the Internet as a "dongle."
--> If it can't detect the dongle, it guesses that it's being
"sandboxed/sandbagged," and plays dumb.
--> If it *does* detect the ``virtual dongle,'' this represents an
indication that it has been let out of the sandbox, and will be
allowed to "play," perhaps with some probabilistic scheme for
trying to "do something evil," so that it doesn't guarantee
detection.
I certainly agree that it will be problematic to prove that you have
"proven" that the program does not contain a virus in an analytic
manner; Turing's Halting Problem and all that...
There are, of course, ways of combatting the scheme that I have
suggested, corresponding roughly to a "capabilities" system.
For instance, one might forbid access to the program to files outside
of some "safe" zone, or forbid access to the Internet outside of
certain ports and certain domains.

It was, but not any more. With linux-2.2.x (not sure about 2.2.0, but
definitely for 2.2 releases of the last several months) and glibc-2.1,
you get a true vfork. Because of the code implementing clone already
in place, it was a very small addition to the kernel.

Perhaps you should take a look at perror() and strerror(). It seems,
these function can save you a lot of work. :-)

You probably missed the "what is object oriented programming" thread a
couple months back; that displayed fairly nicely how well-defined the
"TAO" would-be-OS's specifications were.
If you think that it is bizarre that you would see things that I wrote
that you assortedly agreed with and disagreed with, then there are
several possibilities:
a) I may have some inconsistent positions, or
b) You may have some inconsistent positions, or
c) Something else may be happening that makes it appear that one of
our positions is inconsistent.

All unlink(2) does is deallocate an inode from a filesystem.
This doesn't necessitate a disk write. My understanding is that
the device superblock is read into memory when its filesystem is
mounted and the freeing of the inode is done there. At some
point the superblock is locked and synced to disk, but I don't
know what criteria the kernel uses for that.
Ultimately the speed of an unlink probably depends on whether the inode
of the file to be unlinked is in the inode cache.
