Loading (then unloading) e100.ko fails the first few times (i.e. the
driver claims one of the EEPROMs is corrupted). Thereafter, sometimes it
fails, other times it works. Sounds like a race, no?

yes, or something like that.  I think you may have a piece of eeprom
hardware that is either "slow" or slightly out of spec.  I wonder if
the hrt kernel makes udelay(4) much more like 4us than the regular
kernels.

can you try adding mdelay(100); in e100_eeprom_load before the for loop,
and then change the multiple udelay(4) to mdelay(1) in e100_eeprom_read

On an unrelated note, insmod_100.txt is truncated at the beginning, and
insmod_110.txt is truncated in the middle (!!) cf. line 14. What would
cause klogd to behave like that?

usually its because whatever is printing is printing too fast or too
much at a time.
