I notice that whenever I try to access the DOC, the process [nftla] starts to use up all the cpu time. Right now I am suspecting that it is the problem with the filesystem on the DOC. Sometimes, after running e2fsck on my ext2 partition on the DOC, the problem just goes away. I have this problem both in 2.4.22 and 2.4.17, both patched with mtd snapshots of different dates. Therefore, I think it is a problem with the mtd driver. Any ideas are appreciated. Selwyn
