SPARC SUN with SUN OS 4.0EXPORT crashes with "panic: diskquota"

[Stan Corbin]

Our Sun-4/280 running 4.0 is also crashing with "panic: diskquota", but it
happens at least once per day when quotas are enabled.  With quotas
disabled, it crashes about once per week with "panic: vn_rele".

We reported the problem to Sun SEVERAL weeks ago, but have not received
any satisfactory results (surprise, surprise :-|  ).  They seem to think
it might be a hardware problem.
