epic100 && >=2.3.99pre7 && ping -f == reproducible lockup

2.3.99pre6 works fine, >= pre7 is broken
2.4.0-test1 is current kernel

Eth is generally broken, no communication with other hosts whatsoever.
The hosts are on local lan with 192.168.1.xxx ip's. A ping -f to another
host results in a hard lockup with the reset button the only option.
I've tried "debug" on the boot command line and gdb with no joy. Strace
will fail in poll([{fd=3, events=POLLIN|POLLERR}], 1, 10) = 0 with just
"poll(" when it freezes. Both my hub and the remote host show no
activity during the ping flood.

eth0: SMSC EPIC/100 83c170 at 0xc901c000, IRQ 11, 00:e0:29:22:4f:18.
eth0: MII transceiver #3 control 3000 status 7809.

Any suggestion on how to get a better trace....? Standing ready to crash
my machine repeatedly with extreme prejudice...
