I have the BIOS set to IDE mode; I found the other problem "the hard way" and the workaround... Here's the dump from the BTX death - leading zeros omitted, and hand-copied (hope I didn't screw it up!) INT = 00d err = 0 efl = 30086 eip = 14db eax = 8 ebx = 1970 ecx = c350 edx = 81400008 esi = 3684 edi = 0 ebp = 364 esp = 349 cs = cf000 ds = 9b00 es = 14000 fs = 0000 cs:eip = 2e 0f 01 16 8d 07 0f 20 ....... ss:esp = 08 00 00 00 c0 9a 40 81 00 00 50 Hope this helps. - -- Karl Denninger (karl@denninger.net) Internet Consultant & Kids Rights Activist http://www.denninger.net My home on the net - links to everything I do! http://scubaforum.org Your UNCENSORED place to talk about DIVING! http://genesis3.blogspot.com Musings Of A Sentient Mind On Sun, Sep 16, 2007 at 03:46:31PM -0400, Howard Goldstein wrote: > Karl Denninger wrote: > > Hi folks; > > > > I have a new Intel ICH7 board here that has Quad-core support. > > > > It works well EXCEPT.... > > > > It has an on-board RAID controller with some internal buffer memory. > > There's a known issue with an interrupt storm when the ICH7R is > configured for AHCI or RAID, and a pr was filed back in July(don't have > the number, search for interrupt storm on atapci1+).
