Package: src:linux
Version: 4.19.171-2
Severity: normal

Dear Maintainer,

Kernel update vmlinuz-4.19.0-14-686-pae causing a hang system after suspend/resume with a lot of: "task XXX blocked for more than 120 seconds" in dmesg.
Previous kernel vmlinuz-4.19.0-13-686-pae works fine.

I also tried recent Debian (bullseye) with vmlinuz-5.10.0-3-686-pae. Same problems.

More logs are here:

Debian 9 issue fixed for 4.19.0-16-686-pae.

Debian 10 issue still presents in vmlinuz-5.10.0-7-686-pae

I've tested suspend / resume with 'linux-image-5.13.0-trunk-686 (5.13.12-1~exp1)' - not working!

Kernel freezes with the same error. Full logs at:


(dmesg.1 logs for 'task blocked')

I'm using Debian 11 clean installation with Debian 10 kernel (Buster, linux-image-4.19.0-17-686). Same configuration Debian 11 with 'linux-image-5.13.0-trunk-686 (5.13.12-1~exp1)' from experimental for testing.

I checked again vmlinuz-4.19.0-14-686 kernel and it works fine. Note sure why it failed back then (maybe my mistake). But all recent kernels from 'bullseye', 'bookworm' and 'sid' failed. Last tested from 'bookworm' failed:

linux-image-5.14.0-1-686_5.14.6-2_i386.deb

I've tested following:

v5.0.2
v5.2.17
v5.3.15
v5.4.19

with debian patches applied, and compiled for Pentium M CPU - suspend / resume working fine!

compiling:

v5.10.70
v5.10.1

makes 'task blocked for..." appear. Seems like this is 5.10 kernel issue.

I'm trying kernel git 'bisect' for the first time, to find the exact bug causing this issue. Wish me luck!

[69a74aef8a18eef20fb0044b5e164af41b84db21] e100: use generic power management

Author: Vaibhav Gupta <vaibhav...@gmail.com>
Date:   Mon Jun 29 14:59:43 2020 +0530

    e100: use generic power management
   
    With legacy PM hooks, it was the responsibility of a driver to manage PCI
    states and also the device's power state. The generic approach is to let
    PCI core handle the work.
   
    e100_suspend() calls __e100_shutdown() to perform intermediate tasks.
    __e100_shutdown() calls pci_save_state() which is not recommended.
   
    e100_suspend() also calls __e100_power_off() which is calling PCI helper
    functions, pci_prepare_to_sleep(), pci_set_power_state(), along with
    pci_wake_from_d3(...,false). Hence, the functin call is removed and wol is
    disabled as earlier using device_wakeup_disable().

Building a recent kernel without a bugous patch makes a working machine!

[v5.10.70] + [debian patches 5.10.70-1_bpo10+1] + [revert 69a74aef8]

Suspend / resume works!
