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. jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000000: 0x00b0 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000004: 0x00b0 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000008: 0x00b0 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0000000c: 0x00b0 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000010: 0x00b0 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000014: 0x00b0 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000018: 0x00b0 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0000001c: 0x00b0 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000020: 0x00b0 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000024: 0x00b0 instead Further such events for this erase block will not be printed a dozen of times...
