Yes, only the kernel changed. In the time since my original post in February I found the reason for the problem: The problem is caused by the patch "nfsd: vfs_llseek() with 32 or 64 bit offsets (hashes)". A discussion of regressions caused by this patch can be found in the thread http://comments.gmane.org/gmane.comp.file-systems.ext4/37022 (started by you :-). I solved the problem by disabling the 64-bit hash-extension. I have not checked whether a better solution was found since then. > > Have you considered upgrading your Solaris version?

I think this makes the proposed dump obsolete?
