Since updating to Debian Stretch I'm seeing these kernel messages while system boots up (in prior version's they did not show up at all):

dmesg -k -l err,warn

Seems like some firmware issues are there which I am unable to fix despite trying dpkg and dpkg-reconfigure solutions I found online.

How do I fix that?

  • Broken ACPI firmware is the norm, not the exception. You might be able to fix it eventually with a BIOS upgrade, but new BIOS versions may add new problems. If your machine works as it is it might be safer to just let it be. Either way it's a hardware problem not a Linux one. – Satō Katsura Oct 16 '17 at 9:26
  • would that mean I m having hardware issues related to radeon,iwlwifi & possible other components? – techie_28 Oct 16 '17 at 10:07
  • You can in fact run into all sorts of issues because of ACPI, but you probably won't. As I said: if it works as it is just let it be. – Satō Katsura Oct 16 '17 at 10:32
  • I wont upgrade I just want to know about the situation – techie_28 Oct 16 '17 at 10:42

    This just means the problem (whatever that might be) went undetected until you upgraded. Most ACPI firmwares have bugs. The vast majority of these bugs go undetected. A minority of them are fixed from time to time, when you flush a new version of BIOS. Sometimes new versions of the kernel get smarter and detect (and complain about) some of these bugs. Ask on the kernel list what that error means if you're really concerned about it. – Satō Katsura Oct 16 '17 at 10:48
