[Seiichi Nakashima]

Hi.

I update to linux-2.2.20 + patch-2.2.21-pre4.
before I used linux-2.2.20 + patch-2.2.21-pre3, and worked fine.
linux-2.2.21-pre4 is normal end to patch, compile and install, but bootup failuer.

these messages displayed on console, and hung up.

I remember this was the one-and-zero stuff from last evening or
whenever. Can someone remember? It was just some 0 which had to be 1.

According to other reports, it would appear that this change:

is the problem. Reversing it (i.e. changing the i=0 to i=1) should allow
you to boot again.
