I have an updated version that I wrote to work with 2.1.x. It now
has a user level system call to retrieve physical buffers. The /proc
interface needs some cleanup, too.
You can find it at:

I plan to get the patch up and running with 2.2 and work to have it
brought into the 2.3 tree when it comes out. This is functionality that
should be exposed to applications that need physical memory.

Good point. But since there was only a few seconds difference even
between the uncached -j2 and the cached -j4 it really seems
irrelevant.
Is there a command to clear the cache, or do I need to reboot each
time?

Could be, but it is puzzling that he can compile and otherwise use the
system without undue problems. Hardware problems would also show up
when working in other operating systems on the disk, I would think.
Another possibility is that the file system has become corrupted somehow
at some point during those two weeks, and the problems are a symptom of
that.
A suggestion for John: Run fsck on the Linux partition (assuming it is
an ext2 partition, use e2fsck). You don't want to run fsck on a mounted
partition, and the root partition will be mounted. This suggestion may
sound strange because fsck was run for you when booting up (because you
did not shutdown cleanly), but the root partition was mounted at that
time -- it had to be, since fsck is on your Linux partition. Since you
mentioned you have RedHat, boot a kernel image on a floppy, typing
'rescue' at the LILO prompt, then feed it the RedHat Rescue disk when
it asks you for it (if you haven't made a rescue disk yet, make one
first). The rescue disk creates a RAM disk image that contains fsck, among
other programs. Your HD root partition won't be mounted when you boot
from a floppy, so run 'fsck -f /dev/hda4' (if your Linux partition is
hda4). If you get a clean report, then your filesystem is probably
not corrupted. If you get errors, fsck will hopefully fix them, and
that will hopefully get rid of your problems. After running fsck, you
can reboot normally.
Good luck!
Regards,
Marty

Well, I have used cdrecord to burn two CDs with 2.2.2. Nevertheless, I am
having strange problems with 2.2.1 and 2.2.2. I occasionally get paging
exceptions when the system shuts down after the disks have been unmounted.
More seriously, and possibly related to your problem, I could not simply
copy /usr to an MO device when making a backup without the paging exception.
That was with 2.2.1. With 2.2.2, I cannot even make access to the MO
device. Both mount and fsck think that the superblock is corrupted.
Cheers,
Mike Dowling

Actually, I got the RPM from updates.redhat.com. (or maybe it was
rawhide.redhat.com?)
but anyway it was a redhat server. I snarfed it two or three weeks ago though,
and
only now found the time to try it, maybe I should look for a newer version from
redhat.

I'm going to see what a fresh download of the rpm from RedHat does, then,
if that fails, I'll try compiling from the tar.gz source myself.

They used to have an evaluation copy for Linux. When I tried it it did
work ok. I didn't like it as much as Purify (not available for Linux)
and since I didn't really need such a tools on Linux I didn't actually
buy it.

There have been some changes in the semaphore code in 2.2.2 with the
effect that compilation breaks on most architectures. Try 2.2.1.

OK, this has probably been asked before, I can't can't seem to find anything
on the subject when searching through DejaNews. Is there a way to setup Linux
so that when a user is logged in via ttyX that they are a member of a
particular group Y? I would this this would be useful for allowing access to
certain devices depending on what terminal you are logged into (for example,
if you are logged into the console, you should have access to /dev/dsp*, if
you are logged into a particular serial line you might have access to some of
the /dev/hd* devices).

the guys working on the Matrox Meteor driver have a preliminary

It's about time this patch or something with equivalent functionality went

Hi all,
I'm in trouble with my Acard SCSI-3 (6710S) and linux kernels
2.2.x. The card is correctly detected, but the boot process (or
atp870u.o module insertion) stops after the following message:
aec671x_detect:

I know that this cards works perfectly with kernel 2.0.37.

Doesn't sound goofy at all, assuming you mean `strtol.c' not `strol.c'.

I don't use either RH or gcc 2.8 (Debian & egcs here), so I can only
guess, but your problem might be that RH ships libc with debugging
symbols (gcc -g). If so, gdb will try to find the source; otherwise it
shouldn't. So try stripping the library. (How and whether to strip
libc.so.6, and how to test the stripped version without hosing your
system in case of failure, and how to replace the real one with the
stripped one safely once you have tested it, are left as an exercise
for the reader.)
