So it looks like HW issue that can be ignored at best. After reset SMBus continues to work. The only question is, should we provide an option to shut up those errors; assuming user knows (s)he has buggy controller there is no reason to spam dmesg with known issue. Will patch be accepted? I will emit first occurence of this error to let users know something is fishy and supress further ones. But this has to wait for next week, it is already too late here.
