As far as I know, the only use case for Host Notify on i2c-i801 is the touchpad on certain laptop models. If the touchpad still works OK after disabling Host Notify, I guess you are good. I'm fine with blacklisting, at least until the bug is understood and fixed. Out of curiosity, does the bug still happen if i2c-i801 is built as a module? If it does, then one thing you could test is to boot with i2c_i801.disable_features=0x20, then rmmod i2c-i801 and load it again but without disable_features=0x20. If it still hangs then at least you would have a running system to diagnose the problem. If we knew where it hangs when maybe we could come up with a fix or at least workaround. -- Jean Delvare SUSE L3 Support
