My guess is that this is a coherency issue rather than a timing issue.
The SMP kernels are far more careful about ensuring

Hi,
a few weeks ago, I had a coworker which wanted to ls and have the
directories listed first...
He ended up with a bash function :
lx() {
\ls -FGhl $@ | grep ^d | cat;
\ls -FGhl $@ | grep -v '^d\|^t' | cat;
}
I though better of it and cooked up a patch for ls :
Hello,
I was toying with a programmable PCI card and wrote some code
which DMAs a small block of data to the host, and then interrupts the
host. The host checks the end of the block, and sees if it gets the
value it expects.

The chipset probably uses PCI bus (MSI-like mechanism) to deliver the
interrupt from the IO APIC to the local APIC, which means that the PCI

If you've got a small enough amount of traffic, you could use
tcpdump to
snarf the headers and then use your favourite scripting languge
to look for
repeated sequence numbers (retransmits) and repeated acks (lost packets);
but I suspect this would be too slow for most purposes.
Yeah, we

These types of statistics aren't kept.
Generally, they are used only by network researchers, who hack
their stacks to get them.
They usually do not make it into commercial product distributions
for performance reasons, and because every byte added to a tcpcb

Would be interesting if CURRENT does panic too ...
Well, it does. Tested on -CURRENT supped today at about ~1 EST.
The panic message is different this time: panic: m_free detected a mbuf
double-free.
Still, I couldn't reproduce it after swapping NICs.

I don't know if this a widespread opinion, but I believe that saving
core files in backup tapes is a waste of time and space, often a big
waste. Consider that Emacs itself can fill hundred of megs of disk
space with just one core dump, that if you don't bother to debug, it
will likely sit there

Other recent examples include libxmms.so and libintl.so.
