There were many responces to this question. About half had never experienced
the problem and half had seen the problem varying from ocassionally to

Several said the problem is fixed in 2.5

There were two patches sugested, 102729-01 and 102332-01. the first merely
added a S99aui_tpe file to rc2.d which, you guessed it, added
a ping command to the boot procedure. The other patch, appeared from the
meager description, was for classic systems only and I did not try it.

one suggested : eeprom tpe-link-test true and reboot

one suggested eeprom tpe-link-test false and reboot.

a couple of people thought the problem may be in the switching hub, but
we have completely dumb hubs.

I decided to stick with my orginal solution.
