Cool, thanks.

Happy to do so!

 Grrr!!  Had i been more observant, this would not have taken nearly so
long to figure out.  I had previously noticed that the 10/100 Mbps
built-in interfaces were coming up as "10baseT (autoselect)." I decided
i'd come back and address this after i had solved the kernel panics.

 But i hadn't read the kernel config closely enough to realize that the
generic kernel has been using the wrong damn driver ("de" rather than
"tlp") this whole time.

  sarasvati just booted the 1.6_BETA5 kernel without any intervention and
then recognized the same 10/100 Ethernet interfaces as "tlp" rather than
"de".  I noticed this during the boot, and after sarasvati had come up
completely, i ifconfig'd the "tlp" interfaces by hand. (Necessary because
there were no files named "ifconfig.tlp[01]" in /etc, but rather
"ifconfig.de[01]".)

 I then did the usual test, NFS mount /usr/src, and attempt to config and
compile a 1.5.3 kernel.  And it worked.

 Then i installed a 1.5.3 kernel that was the GENERIC config but with two
changes:

1) The "de" driver was commented out.

2) the following line was uncommented (to match what i saw the 1.6_BETA5 kernel
 report):

options 	TLP_MATCH_21142

I config'd, compiled and installed the new 1.5.3 kernel.

Rebooted with the new 1.5.3 kernel, and tested building a kernel from
scratch on an NFS-mounted file system.  Success! No crash.

 So i believe your guess was correct; the problem lay in the "de" driver.

 The only thing resembling "fault" that might exist in the generic 1.5.3
kernel is its choice to use the "de" rather than the "tlp" driver for the
Tulip 21142/21143.

Obviously, this appears fixed in 1.6_BETA5 kernel.  I believe i noticed
that there will be a 1.5.4 release.  If there are not any other
conflicting factors, would it be a good idea to also alter the 1.5 kernel
to "prefer" to see this particular Ethernet interface as a "tlp" rather
than "de"?

For posterity, i'm attaching boot-time dmesg for 1.6_BETA5 kernel and the
functional 1.5.3 kernel with the "de" driver removed.

Thank you for your help with this.

Now on to paring down the kernel for my DS10! :-)
