This pacth series intended for fixing problem reported by Tony Lindgren <tony@xxxxxxxxxxx> here[1] One of first four patched could fix the problem. Last patch provide event trace so I could resolve problem. It could be applied using 'git am' or 'patch -p1 ...' Patches are rebased on branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux (6e79807443cba7397cd855ed29d6faba51d4c893) Tony, could you check, does the series fix the problem reported[1]? If yes, could you bisect and point commit that solve. If no, could you provide trace output (with or without the patches from series). If no, could you check does i2c-omap.c from commit ca1f8da9ac5ce6e63d8f6933f83fabc1f3f961f4. (the commit before my changes to kernel) work for you? Thank you. Regards, Alexander.
