The system does not allow disabling ASPM, it is a very constrained notebook BIOS, thus the suggestion is nit feasible. All in all the sugesstion seems not favorable for me, as it is unknown how many systems are broken the same way. Having a workaround adviced as default seems oretty wrong to me. > To get a better understanding of the affected system: Could you please provide a full dmesg log and the lspci -vv output? > > > Am 4.

My suggestion to the author is to disable ASPM in BIOS, also because his BIOS doesn't allow Linux to change ASPM settings. > > Linux regression tracking (Thorsten Leemhuis) <regressions@...mhuis.info <mailto:regressions@...mhuis.info>> schrieb am Di., 4.
