BL51E SMBus problem on CentOS 7.7 #197

Closed mlassota closed 3 years ago

mlassota commented 4 years ago

On BL51E there is a problem of non working SMBus on CentOS 7.7: i2cdetect log: i2cdetect.log dmesg log: dmesg.log

There are these lines in dmesg log:

[   11.629163] i801_smbus 0000:00:1f.1: can't derive routing for PCI INT A
[   11.629170] i801_smbus 0000:00:1f.1: PCI INT A: no GSI
[   11.629247] i801_smbus 0000:00:1f.1: SMBus using PCI interrupt

And Anton pointed out this bug to be considered: i2c: i801: Fix Failed to allocate irq -2147483648 error

Are these problems happen with CentOS 7.7/7.8 only? What about CentOS 8.2, Debian, Ubuntu?
