Now it's the third time that one of our NetBSD/i386 machine (running
1.6_RCx, now 1.6 release) hangs up while displaying the above message
in an endless loop.

NIC is (mac part. anonymous :-)):

  ti0 at pci0 dev 9 function 0: Netgear GA620 1000BASE-SX Ethernet (rev. 0x01)
  ti0: interrupting at irq 15
  ti0: Ethernet address: 00:02:e3:xx:xx:xx

which is running fine, otherwise.

I already increased NMBCLUSTERS:

  options         NMBCLUSTERS=16384

The machine is a nfs/web server, but these hang ups occurred randomly
without being correlated to any severe load or network traffic.

- How to avoid these hangs? Further NMBCLUSTERS increase?

- Should these error messages ever appear (== bug)?
