Can't mount after Patch A

I recently upgraded QNXRTP to Patch A and am no longer able to mount my
Linux (ext2) partitions. mount returns the following error messages:

mount -t ext2 /dev/hd1t31.2 /fs/aux

mount: Can’t mount /fs/aux (type ext2)
mount: Possible reason: Can’t access shared library

How do I diagnose/fix what is wrong?

(Incidentally, before installing Patch A, I could mount the partitions
all right, but had to do after bootup. Adding the mount commands to
rc.local would hang the system.)
