Description mark.seminatore 2000-02-17 17:09:59 UTC
I have a few machines (4) which are experiencing intermittent network
card/driver lockup problems.  The machines are dual 600 P3 machines.
lsmod shows the eepro100.o driver is loaded.  When the lockup occurs the
machine is unpingable.  I was able to confirm that an ifconfig eth0 down
up resets the card/driver and restores connectivity.

eth0: OEM i82557/i82558 10/100 Ethernet at 0x9400, 00:D0:B7:20:37:BB, IRQ
  Receiver lock-up bug exists -- enabling work-around.
  Board assembly 733470-004, Physical connectors present: RJ45
  Primary interface chip i82555 PHY #1.
  General self-test: passed.
  Serial sub-system self-test: passed.
  Internal registers self-test: passed.
  ROM checksum self-test: passed (0x04f4518b).

Comment 1 mark.seminatore 2000-02-20 05:15:59 UTC
More info: I find out that the actual chipset on the cards is in fact Intel
82559.  It seems that the driver mis-identifies this chipset and so possibly
disagrees with it in some fashion.  At this time I have replaced 6 NICs with
3C905B and things seem to be working well.  Looks like the eepro100.c driver
potentially needs a tweak.

Comment 2 mark.seminatore 2000-02-25 05:03:59 UTC
The lockups have continued even with 3Com 3C905c network cards.  We now suspect
that there is an SMP problem and have booted the non-SMP kernel on one machine
to test.

Comment 3 mark.seminatore 2000-03-13 07:00:59 UTC
Ok, so now we know that SMP is NOT the problem.  We continue to have lockups
with either kernel version.

Did these stop with the newer kernels in 6.2
