In other words, you're a phoney, a liar and a troll because you were
singing the praises of FF a few months ago because it was propping up
your decrepit XP.

The problem wasn't with any kernel or application, nimwit.

So why was the machine rebooting every 4-days and why did RedHat issue
a FIX for it if there was no problem?

He can't.

He's just trying to change the topic.

That topic again?

Oh yes, a 5 line web page can reboot a 'professional workstation' OS
called XP.

Here is what you said:

<1118347726.064667.37560@g44g2000cwa.googlegroups.com>

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145563

It's recent enough - from 2005.

So what's the "big-story" here? That kernel mode drivers are capable of
taking down a OS. Hardly news is it?

So you were right (sort of) the first time. Were you just talking out
your ass the second time? Like, being sarcastic?

/proc/kcore is described very briefly here:

Quote:

Yes. I continue to claim that privilidged/kernel-mode code can take
down a system.



Quote:

Sarcasm would be correct. Of course I don't believe that a user mode
application would take down an OS. But if the poster was going to
insist that a driver or kernel mode code wasn't causing the crash then
allthat's really left is TAR. So using the process of elimination
(along with a healthy dose of sarcasm) I came to the absurd conclusion
that tar was responsible.


Thanks for the link. Didn't know this about /proc/kcore as I never
needed to use this before.

Quote:
/proc/kcore is like an "alias" for
the memory in your computer. Its
size is the same as the amount of
RAM you have, and if you read it
as a file, the kernel does memory reads.


So out of curiousity... back to the crash reported on RedHat. If the
backup process was reading this file why would it randomly crash? It
appears that the backup app was running as root and reading this file
(in order to back it up) would result in reading the system RAM. It's
only a read operation so the read shouldn't be destructive to the RAM
contents. It's not clear why it would crash some times but not always.

Save your data before. The machine will BSOD

Tried it. No BSOD. No crash. IE simply doesn't display the image with a
width and height of 9999999. Dropping a digit (999999) shows the image
but it's very slow. Dropping another digit (99999) shows the image and
scrolling is sluggish but usable.

Nice FUD though. BSOD... now that would be a lie.

How is it a "lie" when it has been confirmed by other people? Perhaps it
depends on the amount of total memory you have on your system as to
whether it actually crashes or not.

The point here is that a friggin WEB BROWSER has the capability of
potentially crashing a Windows system simply because the platform will
allocate all available memory to trying to display this massive graphic,
even to the point of taking away memory from its core components.


It's a video driver error - it has nothing to do with memory. It works on
my little 64MB nVidia card that's in this box. Sure, it slows things
down, but it doesn't crash. The problem is crappy video drivers

I most certainly don't think so. The video driver causing the BSOD is
*not* the problem, it is the symptom.

The problem is that, for the zillionth time, a bug has popped in IE
where the programmers didn't check their input, allowing IE to request
a too large amount of memory. The attempt to display a large image may
trigger other problems in the video driver causing a BSOD, but the
faulty component is most certainly IE, and therefore the Operating
System itself.

Mart

Except Mart... It doesn't matter if your using IE or not. It occurs
just as readily in FireFox as well. Unless your saying that FireFox has
the same bug?

I disagree. Read on.

If this were true the following code: " malloc(0xFFFFFFFF) " would also
cause a crash since it's attempting to allocate 4.3 gigs of memory.
Given that this is the largest amount of memory a 32-bit application
can request according to your logic this should also cause a BSOD. But
it doesn't crash the OS. It simply returns a NULL pointer.


Quote:

Yes. Some video drivers are likely requesting this memory (see my post
yesterday - search for StretchBlt). When the memory allocation fails
the driver continues on using the NULL pointer.

Here's a scary one from last month where Linux spontaneously rebooted:

leaving a corrupt partition table and disk with errors. There was nothing in

Linux ready for prime time? I think not.

Offcourse not ready for primetime, that is why it's a _rc_ (Release
Candidate) version of the kernel, this feedback resulted in a fix just 3
days later.

News flash: IE is embedded with the OS so tightly that by removing it you
cripple the OS
In other words: An IE fault is a windows fault
You can wiggle all you want, but until you show how to remove IE completely
without crippling windows, this is exactly the case
