I'm curious to know why is the i2c-device being removed.
It's from psmouse_smbus_disconnect().
And this sounds like a known problem, according to the comments in psmouse_smbus_schedule_remove():
/* * This schedules removal of SMBus companion device. We have to do * it in a separate tread to avoid deadlocking on psmouse_mutex in * case the device has a trackstick (which is also driven by psmouse). * * Note that this may be racing with i2c adapter removal, but we * can't do anything about that: i2c automatically destroys clients * attached to an adapter that is being removed. This has to be * fixed in i2c core. */
Fair enough, but the removal happens on resume time, which I found kind of strange. -- You are receiving this mail because: You are on the CC list for the bug.
