The Register: New Itanium stepping has infernal kernel

Reports on developer newsgroups suggest that the latest
chip stepping of Intel’s Itanium processor is causing problems for
Linux developers whose code worked fine with stepping A2.

“Timing issues seem to be the problem, but it is aggravated by
the fact that Intel has so far released few samples of the B1
Itanium, making the process of testing and de-bugging harder than
would be the case otherwise.”

“The Itanium is delayed until the end of this year, Intel
officials said at the Developer Forum a few weeks back.that volumes
would not begin to ship until next year.”
