Hello folks, I'm using a rather old kernel (2.4.27) that has been working quite well in an embedded system. Currently, I am conducting some unclean shutdown tests with different flash disks and I'm running into fs corruption. I'm using the data=journal mode for the root and data partitions. I'm mounting with the 'noatime' option. Would it make sense to go to the latest 2.4 kernel or should I move on to 2.6? I have three different flash disks and none of them seem to have write caching, however one of them has the 'Mandatory FLUSH_CACHE' support - what exactly does that mean?

And if it turns out to be a bug, maybe someone will fix it.> Would it make sense to go to the latest 2.4 kernel or should I move on to > 2.6?If upgrading to 2.6 is feasible for you, it's worth a try.
