Andi:
 Don Zickus and I have been trying to reproduce the problem with
 the config file Fengguang Wu sent to us, but so far have been unsuccessful.

 Given there are 5 other locations in the code that need to be changed
 from [128] to [KSYM_NAME_LEN], and that we still haven't found Fengguang's
 problem yet, I'd be in favor of letting Michal's revert patch 2/2 go forward.

 That would give us time to find the issue Fengguang reported.
