Re: [Linux-ia64] IRQ problems when running McKinley Kernel on Proliant

[Stephen Mulcahy <stephen.mulcahy@hp.com>]

Hi Alex,

Thanks for your response. I've made some inquiries and this is a known
firmware issue that will be resolved in the next firmware release for
this platform, however the timeframe for this firmware release isn't
decided yet. In the meantime, people wanting to run linux on a dl590
may wish to compile an itanium-specific kernel to avoid interrupt
problems.
