Hello,
I have received a regression report on commit 13e3a512a29001c ("i2c: smbus: Support up to 8 SPD EEPROMs") as I was subscribed to some kernel Bugzilla thread and I'm posting it here to make you aware of it.
This thread was

The param mentioned was i2c-i801.disable_features=0x10, which disables interrupt usage of this driver.
Please decide if this is serious enough to warrant a revert.
