The older combination of kernel and fdisk in RH 5.2 can
see no more than 1024 cylinders (when Heads > 16, i.e.,
when LBA is enabled). You have to tell fdisk the correct
value to use, by going into its 'expert' menu.
The problem appears to have been resolved in the newer kernel
and fdisk shipped with RH 6.0.
The discrepancy between geometry reported by RH 6.0 and the
bios is that LBA is enabled. The bios reports the manufacturer's
numbers while RH 6.0 is reporting the number with the LBA
fictitious number of logical heads (255). (You will note
that 16383*16/255 = 1027.xxx).

I am having the same exact problem, and I am also using Redhat 6.0.
I did not have this problem with my 5.2 box. I also get freezes when I
try to mount NFS volumes or Netware volumes (ncpmount freezes as well).
Does anyone have any ideas?

Under RH5.2, there was a problem with one of the C libraries
which resulted in the US/Central time zone malfunctioning.
I don't know if your problem is related. The problem has
been fixed in RH6.0. Under RH5.2, we found substituting
Canada/Central resolved the problem.

The proper way to do this is to use the user's .bash_profile
or .bashrc. If you don't want the user to be able to modify
them, you could make those files unwritable by the user. It
would probably have to be readable and executable by the user
to function.
I suppose you could put complicated code in /etc/bashrc which
would check who the user was and then execute commands just
for that user. But that seems needlessly complicated and
likely to lead to problems.

But... It isn't more susceptible to disk mangling.
I've had a power filaure or reset that caused it to drop into emergency mode
several times... Running fsck /dev/hda<whatever-partition-failed> fixed it
every time.
e.g. On bootup after a reset it complains that fsck couldn't fix a file
system (say... hda3) and drops you into a root password prompt.
Enter the password, type fsck /dev/hda3
Answer <y> to all the questions (Unless you know what it and you are doing
well enough)... And everything's just hunky-dory...
When 98 or NT suffers the same thing, it automatically runs chkdsk (or is it
scandisk..?).
(This is almost excatly what linux does, but linux offers more control, and
therefore the emergency mode is used and manual fscking...)

As will fsck in linux. Their function is almost identical, even if their
form differs.

Doubt it... A *really* doubt it...
The only thing your likely to lose in such a situation is the file it was
holding in its cache at the time and hadn't written yet.

I think you should RTFM...
:)
Type 'man fsck' to start with.

Last time I checked, nobody was put under the gun to use services of
the bank. That's hardly some "slavery".

The "Mindcraft" benchmarks had the effect of exposing a few places where it
was possible to improve Linux.
Exposing a W2K box to public attack can help MSFT find vulnerabilities that
they did not know about.
Those that want to cause *real* damage will leave this publicity stunt
alone, and will wait to use any exploits that they have discovered when
there is general deployment of W2K, and exploiting the vulnerabilities
can allow them to break into *important* systems and steal/destroy
*important* data.
What value is there in hacking into a publicity stunt box?
Far more valuable to wait, make sure W2K doesn't improve, and hack into
a web server that has *credit card numbers.* Getting a piddling prize
now isn't comparable to being able to hack into 15 web servers later
and get credit card numbers that can be used to thieve out hundreds of
thousands of dollars...
(I'm not *recommending* this, I'm just suggesting that this is a highly
likely scenario...)

GDP measures no such thing. GDP measures output. There are differences
of order of magnitude between GDPs of different countries; does it
mean that rich countries invested 10x more labor? They did not, they
just exploited working smarter, economy of scale and automation,
thus _reducing_ amount of labor embedded in a single unit of
production, not increasing it.

Under the SunOS you needed a file called /etc/hosts.lpd
or something similar. If you kept a backup of your old
system, you might check the /etc directory to see if there
were any special files. Also, look at /etc/hosts.equiv,
hosts.allow, and hosts.deny.

sym53c876 refers to SCSI drivers for a Symbios (sp?) SCSI
adapter. These could either be in the kernel or more
likely in a module. There is clearly something wrong. It
could be a hardware problem or something wrong with your
kernel or the module or ???. I assume you do have a SCSI
card, In that case there should be a short program run when
booting before you even get to LILO to boot an OS. It will
indicate a key combination to use the program for diagnostic
purposes. Try doing that and see if you see anything unusual.
You may get a message while Linux is booting about termination
of the SCSI bus, but that probably is not the problem.
You could also have a hardware problem with some device
on the SCSI bus: a hard drive, a CD drive, a tape drive?
You should probably check all the cabling. If you can,
you might try selectively disconnecting the SCSI devices,
but that could be tricky and of course you can't do it for
a hard drive with the system on it.

Don't tell it what driver to use, just check if it's an IDE (ATAPI) or
SCSI. I've loaded RedHat off both with no problems.
