Just to document a strangeness that does not seem to fit the pattern of
UltraSparc III era split:
V210 with USIII family CPUs is still problematic (can not survive
repetituos local git clone, hangs (watchdog detects hang) with
filesystem corruption. This still holds for 3.15 release.
On the other hand, E420R with 4 USII CPUs does not hang and works 100%
stable with git clones etc. Very similar E220R with different config
hangs on that load.
Maybe related to some other options in kernel configs - each config is
unique and they vary intentionally.
