ia64 r255488: panic: uma_zfree: Freeing to non free bucket index. - textdump provided

[Anton Shterenlikht]

After updating to r256624, the system is very unresponsive,
and really unusable - any command (ps, df, top, ls, etc.)
might take up to 1 min to return. However, I could not get
it to panic.

So I reverted back to r255488.
This time I managed to obtain a textdump:
