...s patch cleans up the ASSERT for invalidate_buffers() (modulo the fact that it was missing a ')' at the end of the line) but it hasn't really fixed the whole problem. If a file write is in progress when invalidate_buffers() is called, I get an oops: [[[LVM is in the process of calling PV_FLUSH ioctl => invalidate_buffers()]]] Attempt to refile free buffer Unable to handle kernel NULL pointer dereference at virtual address 00000000 <kdb stuff> refile_buffer cleanup_transaction log_do_checkpoint log_wait_for_space start_this_handle journal_start ext3_file_write do_readv_writev sys...

I think I have this one solved, I hope. I think what Andreas and I are running into are a few different assertions. One being the LVM lvm_do_pv_flush caused assertion which is related directly to invalidate_buffers() being called which then triggers refile_buffer() on a journaled buffer, which appears clean in all other ways according to the checks in refile_buffer(). The following is what I've got in __invalidate_buffers() right now....
