UBIFS assert failed in ubifs_dirty_inode

I am trying use an UBIFS root filesystem on my PowerPC MPC8544 but I am
seeing some intermitent problems with "UBIFS assert failed in
ubifs_dirty_inode" errors.
On the first boot after I program the NAND with a fresh UBI image,
everything seems to work ok.
After that, on subsequent powercycles or reboots, I sometimes see a boot
with the following error:
[ 5.984232] UBIFS assert failed in ubifs_dirty_inode at 377 (pid 1011)
If that message occurs, in less than 1 or 2 minutes, the system is
unresponsive and I start to see infinite messages of:
[ 55.072791] UBIFS assert failed in ubifs_release_budget at 566 (pid 974)

... Goes on forever, or at least the target becomes unresponsive and I
need to power cycle.
It occurs in both the DENX 2.6.31 and the DENX 2.6.33-rc4 (which was
merged the infradead kernel on December 10th).
I have the latest and greatest mtd-utils which I needed to fix my
ubiformat problem.
It occurs no matter whether I ubiformat an ubi image on the target or
whether I install the rootfs via untaring to a ubifs mount point.
Here are the boot messages of one where the ubifs fails:
