 The underlying problem is an incorrect entry for the second on-board
 UART in the interrupt map provided by the firmware which further down
 the road causes hme(4) to fail to attach to the on-board HME.
 6.0-RELEASE will contain a hack to work around the problem (already
 part of RELENG_6 and RELENG_6_0) and a proper solution is being worked
 on.

 That's the interrupt of the second timer embedded in the Host-PCI
 bridge which is set up by the firmware and typically fires before
 FreeBSD can disable it. Read: unrelated and harmless.
