And I certainly don't know of any incompatibility issues save some involving features only present on later kernels, such as extended attributes --- and for the most part ext3 handles that transparently, anyway. > The night after I booted with > the older kernel, the machine had the following in its logs.

You just hit a BUG(), and a bug or assert failure message should have been emitted just prior to this. Such an error in journal_forget() sounds like one of the situations I fixed a couple of years ago, where certain on-disk corruption could cause ext3 to oops internally rather than fail gracefully. But that's not a *cause* of the problem, rather just a less-than-ideal way of responding to it. Also, with a kernel that old, data corruption problems could be due to something as basic as the old IDE driver not dealing properly with new hardware in your system. > So are the ext3 drivers not backward compatible? They should be fully compatible all the way back to the 2.2 kernel (2.0 if you force version 1 superblocks on disk.) --Stephen _______________________________________________ Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
