Hello all,
I'm having the following error on my SMP system:

   ichiic0: timeout, status 0x0
   ichiic0: transaction abort failed, status 0x40<INUSE>

   (ichiic0 = Intel 82801CA/SMBus)

Everything I have found in the archives points to a hyperthreading issue. When the issue first appeared, HT was turned off. I've also tried changing the MP Spec in the BIOS. I've tried the following 4 combos:

   MP Spec: 1.1/HT: Off
   MP Spec: 1.1/HT: On
   MP Spec: 1.4/HT: Off
   MP Spec: 1.4/HT: On

No matter the combo, I still get the same error. I would prefer not to disable ichiic* in the kernel config, but will do so if necessary. Below is a dmesg from the system (MP Spec: 1.4/HT: Off) with MPVERBOSE set in the kernel config. I'm hoping I just missed something and that it is easily corrected.

Thanks for your help,
Shane
