Bugreport: JFFS2 + EBS

[Konstantin Kletschke]

Hm, interesting.

This is 2.6.13 with mtd-cvs from yesterday (actually I produced the
error with other versions also IIRC, trying to reproduce actually):

Kernel says:

JFFS2 warning: (1) jffs2_sum_scan_sumnode: Summary node crc error, skipping summary information.

So all is fine. Where is the Kernel reading 0x00b0 from?

Hm, I will search the archive then... Same Bug seems to be here.
Is the mapping code in maps meant by "flashdriver"?

jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000000:
0x00b0 instead

and so on ...
