Reply-To: Niraj Maheshwari List-Id: Linux MTD discussion mailing list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi, I am using Linux 2.6.10 kernel and mounting the JFFS2 partition from Intel NOR flash after booting the system. These error doesn't appear always, it only comes if we follow the steps explained below. 1. Boot the system and mount the JFFS2 partition. It happens without any error at the first time. 2. Copy enough data to JFFS2 mounted directory so it becomes full. 3. Once the mounted partition is full, we delete few files from the partiti= on. We get following warning when we do that. "jffs2_reserve_space(): Low on dirty space to GC, but it's a deletion. Allowing.." 4. Now again reboot the system now we get below errors while mounting the= =20 JFFS2 partition. jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0013cad4: 0xa6fc instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0013cad8: 0x6e03 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0013cadc: 0x70= cd in stead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0013cae0: 0x0e= 5f in stead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0013cae4: 0x75= aa in stead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0013cae8: 0xca= 04 in stead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0013caec: 0x5a= ec in stead It would be really great if you can help me out to fix this problem.=20 Pl. note that i am only using the JFFS2 support which has come along with the 2.6.10 Kernel.
