I bisected this and tracked it to this commit: commit 6676a847d48ac48908cf467b42da9045b5463a6e Author: Jean Delvare <kh...@linux-fr.org> Date: Sun Dec 16 21:11:55 2012 +0100 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. Signed-off-by: Jean Delvare <kh...@linux-fr.org> Reviewed-by: Daniel Kurtz <djku...@chromium.org> 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.
