dmesg from booting Fedora 32 kernel-5.6.7-300.fc32.x86_64

1. Please describe the problem:
After upgrading from 5.5.17 to 5.6.7 (Fedora 31 and 32), the machine no longer resumes after suspend successfully. The screen comes up, but there's no reaction to mouse or keyboard input and the machine remains inaccessible via network (iwlwifi). Fedora rawhide kernel-5.7.0-0.rc3.1.fc33 suffers from this as well.

2. What is the Version-Release number of the kernel:
5.6.7-300.fc32.x86_64

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :
5.6.6-300.fc32.x86_64
I haven't tried all 5.6 kernels yet, but 

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
1. Boot 5.6.6 or later kernel.
2. Suspend.
3. Resume (press power button).

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:
Yes.

6. Are you running any modules that not shipped with directly Fedora's kernel?:
No.

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.
Attached.

5.6.0-300.fc32 also suffers from this.

Comment 2 Hans de Goede 2020-04-29 09:28:14 UTC 
Ok, so this seems to be a bug in the sony-laptop driver, lets try blacklisting that as a first step towards debugging this.

Can you try adding: "modprobe.blacklist=sony-laptop" to your kernel commandline ?
Comment 3 Hans de Goede 2020-04-29 09:36:01 UTC 
p.s.

After adding the kernel commandline option and rebooting, please do: "lsmod | grep sony" this should not show sony-laptop, if it does then the blacklisting did not work for some reason.
Comment 4 Dominik 'Rathann' Mierzejewski 2020-04-29 11:01:14 UTC 
Plain modprobe.blacklist doesn't work, but rd.driver.blacklist and blaxklist sony-laptop in /etc/modprobe.d/sony-laptop.conf does work. Also, resume works fine without the sony-laptop module loaded. Thanks.
Comment 5 Dominik 'Rathann' Mierzejewski 2020-04-29 20:56:37 UTC 
FWIW, I don't see any commits between 5.5.17 and 5.6.7 touching the sony_laptop module, but there are some new errors in dmesg compared to 5.6.7:
[   18.419670] sony_laptop: Invalid acpi_object: expected 0x1 got 0x3
[   18.422698] sony_laptop: Invalid acpi_object: expected 0x1 got 0x3

[   18.448270] sony_laptop: couldn't set up thermal profile function (-22)

Comment 6 Dominik 'Rathann' Mierzejewski 2020-04-29 21:28:20 UTC 
Instead of blacklisting the module altogether, I added a work-around to unload the module for suspend/resume only:

$ cat /usr/lib/systemd/system-sleep/sony-laptop 
#!/bin/sh
if [ "${1}" == "pre" ]; then
  logger --journald <<__end
MESSAGE=removing sony-laptop module before suspending, see https://bugzilla.redhat.com/show_bug.cgi?id=1829096
__end
  modprobe -r sony-laptop
elif [ "${1}" == "post" ]; then
  logger --journald <<__end
MESSAGE=reloading sony-laptop module after resuming, see https://bugzilla.redhat.com/show_bug.cgi?id=1829096
__end
  modprobe sony-laptop
fi

Seems to work reliably.
Comment 7 Hans de Goede 2020-04-30 09:36:59 UTC 
Hmm, ok so this regression is likely caused by some changes inside the ACPI subsystem. I'm afraid that the best way to track this down is to do a kernel bisect between 5.5.0 and 5.6.0 then. I know this is a bit time consuming, but it really is the easiest way to find the commit which causes this issue.
Comment 8 William Bader 2020-05-04 20:24:11 UTC 
>the best way to track this down is to do a kernel bisect between 5.5.0 and 5.6.0 then.

I bisected it at https://bugzilla.redhat.com/show_bug.cgi?id=1830150#c24
