SOLVED: What are "i801_smbus timeout" and "rmi4" errors?

Hi

since some time (perhaps since 5.5.X), when booting the arch linux kernel, I get errors like these

Apr 20 01:19:12 linux kernel: i801_smbus 0000:00:1f.4: Transaction timeout

and the boot frequently stalls.
If it doesn't stall powertop shows an enormous energy consuption

19.8 W    226.0 ms/s     4926.3       Interrupt      [16] i801_smbus
19.4 W    169.4 ms/s     4845.8       Interrupt      [16] i801_smbus

Any idea, what this might be and how to avoid it?
Thanks

https://en.wikipedia.org/wiki/System_Management_Bus
The kernel module is i2c_i801, check lsmod to see what depend on it.
You could blacklist it and see how the system behaves (and what features are possibly missing)

It also has

parm:           disable_features:Disable selected driver features:
		 0x01  disable SMBus PEC
		 0x02  disable the block buffer
		 0x08  disable the I2C block read functionality
		 0x10  don't use interrupts
		 0x20  disable SMBus Host Notify  (uint)

but I don't know whether any of them might impact your situtation.

Thanks seth!
Yes I did that: blacklistet i2c_i801 on the kernel command line and everything was back to normal again.
It seems there is a conflict between i2c_i801 and hid_rmi for managing the lenovo thinkpad touchpad, see
https://lkml.org/lkml/2017/6/26/479 and here:
https://www.spinics.net/lists/stable/msg224406.html. With one of the two disabled, it works again.

Re: SOLVED: What are "i801_smbus timeout" and "rmi4" errors?

hello, i have a similar issue, as the journalctl show me this

Nov 08 00:52:32 lgtegetege kernel: i801_smbus 0000:00:1f.4: Transaction timeout
Nov 08 00:52:32 lgtegetege kernel: i801_smbus 0000:00:1f.4: Failed terminating the transaction
Nov 08 00:52:32 lgtegetege kernel: i801_smbus 0000:00:1f.4: SMBus is busy, can't use it!
Nov 08 00:52:32 lgtegetege kernel: i801_smbus 0000:00:1f.4: SMBus is busy, can't use it!
Nov 08 00:52:32 lgtegetege kernel: i801_smbus 0000:00:1f.4: SMBus is busy, can't use it!

i still dont see any problem with this but in lsmod it looks that nothing depends on it, should i blacklist it too?
