generating a trap 12 panic. The code blindly assumed that in the event
of a transmit error, the packet that caused the error would still be
at the head of the driver's transmit queue (sc->xl_cdata.xl_tx_head).
However in the case of error 82 (which indicates that a transmit error
occurred after part of the transmit FIFO memory has been reclaimed)
this is not true: the TX queue has already been flushed, and the
pointer to the head of the queue is NULL, so trying to dereference
the pointer to find the transmit descriptor address causes a crash.
The code now checks for a NULL pointer before trying to reload the
chip's download pointer register. There may still be error messages
printed warning of the transmit error, but no panic should occur.
Note that this eror code is only generated with "cyclone" chipsets
(3c900B, 3c905B, and presumeably the 3c980 server adapter). It should
only appear during periods of heavy traffic, probably only on
non-switched networks.

4.1.4. Experimental Protocol
A system should not implement an experimental protocol unless it

the protocol with the developer of the protocol.

Ensure that three of the structures are the size that binutils writes

problems like these.

linker would try to load an ELF shared library if it found one.
Note, this change also fixes the same thing in "ld", because the
code is shared.
For "ld" there is still a problem with ".a" libraries, which cannot
be distinguished by name. I haven't decided what, if anything, to
do about that.
type numbers in vfs attach order (modulo incomplete reuse of old
numbers after vfs LKMs are unloaded). This requires reinitializing
the sysctl tree (or at least the vfs subtree) for vfs's that support
sysctls (currently only nfs). sysctl_order() already handled
reinitialization reasonably except it checked for annulled self
references in the wrong place.
Fixed sysctls for vfs LKMs.

it in non-Lite2 code. Initialize it to -1 instead of to 0, since 0

NetBSD uses strcmp() to avoid this ugly global.
Our write protection of the kernel text on i386's doesn't actually
work in many cases:
- use of the 4MB page completely breaks it.
- CR0_WP isn't set until just before init is started, so the kernel
text is not write protected during kernel initialization.

Device-drivers receive the call through d_strategy, if they have
D_CANFREE in d_flags.
This allows flash based devices to erase the sectors and avoid
pointlessly carrying them around in compactions.

>decision is, I'll respect it.
Another chance to architect people's principles...I can hardly wait. Seems
quite appropriate for a Sunday - I just need to get one of those collection
plates (and money envelopes) so I can profit, too. :-)
Tcl stays in /usr/src for now, but it needs to be kept up to date; same
for perl. If Jordan doesn't have "setup" (written in tcl) ready for 3.0,
then tcl will be yanked prior to the 3.0 release (and made into a port).
As for the ports tree only supporting the last FreeBSD release, this seems
sensible to me. The "ports" have always been a moving target between releases
and the problem is only going to get worse when we expand to supporting other
processor architectures. In any case, Satoshi is and always has been in charge
of the ports tree and whatever he wants to do with it (within reason :-)) is
his decision.
Does this cover the issue completely? I admit to deleting messages in this
thread with unusual fervor (people have FAR too much time on their hands!).
There's a fair bit of reasoning behind the above, but since everyone is sick
of arguing about this, I'll spare you the analysis.
