I bisected this and tracked it to this commit:
commit 6676a847d48ac48908cf467b42da9045b5463a6e

i2c-i801: Enable interrupts for all post-ICH5 chips
I did not receive a single bug report after interrupt support was
added for a limited number of chips. So I'd say the code is good and
should be enabled for all supported chips, that is: ICH5 and later.

I've tested by building 3.9.2 with that single commit reverted, and it
boots without issue.
According to lspci I have:
00:1f.3 SMBus: Intel Corporation 631xESB/632xESB/3100 Chipset SMBus
Controller (rev 09)
Which has PCI ID 0x269b (ie PCI_DEVICE_ID_INTEL_ESB2_17).
For now I will either revert this commit in my kernel builds or
blacklist the module on these machines (I haven't decided which I prefer
yet).
Obviously, I can reproduce this reliably, and am happy to test.
Cheers,
Rob N.
