I have a Ultra-1, with the 2.4.19-pre3 working fine for 4 months, i could
send you the kernel (but is a 5 Mb file), or you can compile a new keernel
with this patch:

I had a quick look at this issue... mostly because I've set up my
U1/170E to be my fiancee's web/email client and the hme would wedge up
after a little web browsing, with a continuous loop of:
NETDEV WATCHDOG: eth0: transmit timed out
eth0: transmit timed out, restting
eth0: Happy Status 03010000 TX[000003ff:00000101]
eth0: Link is up using internal tranceiver at 100Mb/s, Half Duplex
At any rate, I played around with enabling some of the driver's debug
#defines and noticed I couldn't lock it up anymore afterwards. I
reduced it down to just #define TXDEBUG ... then #undefing TXDEBUG and
putting udelay(5) below the TXD()s in happy_meal_tx() ... the udelay(1)
below all three... then one at a time. In the end, I've gotten a
one-liner workaround (disclaimer: "works for me") that seems to make it
go away.
It can still be any number of things, with timing or compiling issues
being (in my mind) the most likely. In the meantime, those of you who
want to try and see if this helps you out are welcome to do so...
