More complaining to MoBo vendors needed
Maybe we GNU/Linux users should start to complain more to motherboad manufacturers when there is a problem in GNU/Linux because of badly coded BIOS. If they don't see demand from GNU/Linux users they obviously don't think it is worth supporting it properly. But if there was much more pressure, especially in this case when there are so many people affected, we could become a visible group of users.
Thank you for bisecting this
Credit where it's due - thank you for bisecting this Michael (yes I'm one of the ones who was asking you for this). However what to do about this? The majority usually prefer stability to features.
Also fun to see in some tiny way I contributed to the workaround...
So pre-PCIe hardware is unaffected - that's also good to know.
3 of my machines don't have PCIe, so at least they cannot be affected by this.
Is there a specific line in dmesg that shows that a machine is affected? E.g. "ASPM disabled in BIOS - ASPM ignored.", or similar?
