Description Bryan Leopard 2001-08-14 20:12:33 UTC
Under some conditions the eepro100 driver (v1.09j-t, rev 1.36) included 
with RedHat (Roswell) may complain that the EEPROM checksum is invalid and 
then set the MAC address to all F's.

The checksum is supposed to be BABA.

It appears to misbehave under the 2.4.7 and 2.4.6 kernels.

Comment 1 Arjan van de Ven 2001-08-15 17:23:59 UTC
During an investigation of the eepro100 driver in the last few days several
issues were found (and fixed) that could explain such behavior. These fixes will
be in a kernel with version tag 2.4.7-2.1 or later, and such a kernel can be
made available on short notice to Compaq for testing if desired.

Comment 2 Glen Foster 2001-08-15 19:56:35 UTC
This defect is considered MUST-FIX for Fairfax.

Comment 3 Arjan van de Ven 2001-08-27 11:21:17 UTC
Have you used the e100 driver before ? It writes to the eeprom and might
have left it in an invalid state

Comment 4 Bryan Leopard 2001-11-14 21:26:53 UTC
Per info on the ia64 mailing list this was caused by some kernel bug. Have not 
experienced this failure since the 2.4.7 kernel.
