I have taken another look at this, and can confirm the following:

1. 2.5.67 works as expected.
2. 2.5.68, 2.5.69, and 2.5.70 do not.
3. ext2 vs. ext3 for /boot: no effect (ie, .68, .69, .70 demonstrate the
problem independent of the filesystem used for /boot).

Relative to a 2.5.68 pure BK tree, the deltas from 2.5.67 to 2.5.68 are:
1.971.76.10 /* 2.5.67 */
1.1124 /* 2.5.68 */
The patch exported by BK between these 2 revs is 297K lines ( a sizeable
haystack ). Any ideas about where I should dig for my needle first
would be welcomed...


Gory details about my hardware & software follow...
