we're using Donald Becker's "3c900.c:v0.37 12/20/96 becker@cesdis.gsfc.nasa.gov\n"
driver with Linux-2.0.29 for 10 PPro200 PCs with 3Com Boomerang cards.
performace is great (esp. compared with the non-busmaster driver)
but now we got problems for the 2nd time on two of the PCs (all are in the
same network; connected to the same hub) which started to show up the
following messages:

the "Transmitter encountered 16 collisions" showed up only once and then the
"transmit timed out" etc. message repeated every few seconds filling up the
logfile until rebooting (doesn't respond anymore to "ping" etc).
note that
- this happend almost at the same time for both PCs (might be an external trigger?)
but the other 8 machines had no problems
- we had this problem once before for 2 other PCs: again starting almost at the same
time, once showing the "encountered 16 collisions" and then only "transmit timed out"...
- all the PCs have been remotely rebooted at the same time (+/- a few seconds),
so the "same time" might be an effect of "same uptime" instead of
an external trigger too.
- on one other PC (#5) which never showed network problems so far we got
Feb 16 19:17:19 maya kernel: floppy0: Unable to allocate DMA memory
Feb 16 19:19:44 maya kernel: floppy0: Unable to allocate DMA memory
one time after we installed the bus-master driver (never happend with the old driver
and never happend again so far; but OTOH we're using floppy only *very* rarely).
any idea what to try or test ? is there a newer version of this driver available?
btw: 8 of 10 PCs are single-PPro200 with 128MB, two are dual-PPro200 with 256MB
(running SMP kernel) and we have the same problems for both types pf PCs
in the mean time 2 more machines suffered this problem once and one machine
twice now (but no more coincidences in time) :-(
thanks,
Harald
