ext3 + autofs4 yields kernel oops



I recently applied the ext3-2.4-0.9.6-249.gz patch to an otherwise unmodified official-from-Linus 2.4.9 kernel. I built both ext2 and ext3 in as modules, did the "tune2fs -j" incantation, and rebooted.

Mounting / as ext3 worked fine. But a few seconds later, my startup scripts tried to launch a squad of automounter daemons, and that didn't work so well. A stream of kernel oopsen follows, all apparently having something to do with those automount processes. I've attached a copy of those messages below.

When examining these messages, observe that I am using autofs4, not autofs3. That implies a different set of userspace tools as well as an "autofs4" kernel module. Note, though, that the autofs4 module is a standard part of the 2.4.9 kernel. Perhaps the ext3 patches create some sort of conflict with the autofs4 kernel module?

It is also worth mentioning that the oopsen appear when using the ext3-patched kernel even if the no ext3 filesystem is actually being used. If I change /etc/fstab to request ext2 mounting, the oopsen still appear. Even if I use tune2fs to actually remove the journal, restoring the filesystem to pure ext2, the oopsen still appear. I've had no choice but to revert to a non-ext3-patched kernel. :-(

Any advice would be much appreciated. If there is additional information you would like to see, you need only tell me how to collect it and I will oblige.
