    Unfortunately, now the system just freezes when doing *a lot* of read
    operations on the NFS share (grep -r foo again). I don't know if it's
    related to your patch or something else, debugging is kinda hard at the
    moment, as it's a Xen DomU (no netconsole; serial redirection magic still
    not working), it'll take me a while to figure out what's going on here.

    FWIW, I'm able to compile kernels over this very same (readonly) NFS
    share, only "grep -r" was able to trigger the freeze.

    BOFH excuse #323:

    Your processor has processed too many instructions. Turn it off immediately, do not type any commands!!
