CPUs stuck during boot after 19.10 upgrade to 5.3.0-40

[Michael]

lsb_release:
Ubuntu 19.10
Release 19.10

Boot process stops at blank screen with .....[76.575608] watchdog: BUG: soft lockup - CPU#0 stuck for 23s! [systemd-udev:411] [48.523054] watchdog: BUG: soft lockup - CPU#3 stuck for 1s! [swapper/3:0]

I rebooted holding the shift key and was able to reboot into 5.3.0-29 which runs with no issues.

Status changed to 'Confirmed' because the bug affects multiple users.

Which hardware are you on?

I'm seeing exactly the same behavior on Ubuntu 19.10 and KDE Neon on Lenovo Ideapad S340-14API with AMD Ryzen 3200U / Radeon Vega Mobile Gfx on board.

The 5.3.0-28 kernel works just fine, while 5.3.0-40 shows the following effect:
 - on Ubuntu 19.10, booting never ends due to random "BUG: soft lockup - CPU#xx stuck for 23s! [system-udevd:383]" events, thus causing various jobs/services to hang forever;
 - on KDE Neon, I'm seeing failures with amdgpu driver somewhere in amdgpu_mm_rreg with a call trace ending with gfx_v9_0_set_safe_mode() call.

Appreciate any input.

Just for the record - the only way I can boot 5.3.0-40 on the hardware mentioned in previous message is to use the "nomodeset" parameter, obviously leading to absence of GUI.

I am using a Lenovo IdeaPad L340 with AMD  Ryzen 3 processor and Radeon
VEGA graphics by AMD

Glad its not just me.

Same issue on AMD Athlon 300U (basically a Ryzen 3). 5.3.0-29 works, 5.3.0-40 doesn't.

[Ron Bentley (rtbentley)]

I am joining the chorus only to confirm this seems to be related to a specific set of hardware. I got the same result on an Acer Aspire 5, AMD Ryzen 3 3200U with Radeon Vega Mobile Gfx: 5.3.0-40 fails to boot (or fails to boot to the full graphical login) and 5.3.0-29 continues to work just fine.

Me too on AMD hardware:

AMD Ryzen 3 3200U with Radeon Vega Mobile Gfx

can boot and run 5.3.0-28 but NOT 5.3.0-40 installed last night at recommendation of Discover app on Ubuntu 18.04

[Jan Troll (jantroll)]

I have the same problem with 5.3.0-40 kernel on Ubuntu 18.04.4 , 5.3.0-28 works without any problems.
My hardware is:
AMD Athlon 3000G
ASRock B450M-HDV R4.0 with R3.70 UEFI BIOS
8GB 3000MHz DDR4 RAM
240GB Crucial BX500 SSD

Can confirm. HP Notebook with AMD Ryzen 3 3200U with Radeon Vega 3 GPU

[Venzislav Ivanov Stefanov (venzislav)]

The same thing with my hardware :

lenovo notebook LENOVO S340-14API / 81NB008ABM

AMD Dual Core R3-3200U Processor, 2.0 GHz (1M Cache, up to 3.5 GHz)
8 GB DDR4
256 GB SSD | М.2 PCIe NVMe (2280)
AMD Radeon Vega 3

[Terence Ho (dummy800)]

The latest kernel 5.3.0-42 seems to have resolved the boot problem

[Ron Bentley (rtbentley)]

I can confirm this seems to be resolved with the 5.3.0-42 kernel packages.
