Mounting a CDR containing an ext2 file system under 2.3.51 fails (mount -t ext2 /dev/cdrom /cdrom). This same CDR works fine under 2.0.36. The block size for the ext2fs file system on the CDR is 1024 bytes (this allows the CDR to store more small files than an ISO9660 file system can store using the normal 2k block size). Below are the messages logged and the output of ksymoops.
Thanks, Rik
