This issue seems to be real
(not caused by disk, issue mentioned in prev. message).
Connecting disk directly to host (vs via disk enclosure w/ sata-sata bridge),
doesn't change symptoms regarding nfs: it still stalls.
Nfs stall is usually seens, after building a few kernels;
especially if nfs client also does other use of nfs mounts:
e.g. `du usr/src; du /usr/obj'.
A new forced crash dump will be uploaded later today,
this is test case without disk CRC errors.
(I guess present crash dump (*.23) reflects nfs/networking problem,
i.e. that is isn't affected by disk CRC errors though)
