Docker Desktop Rosetta lock-up while accessing /dev/mem

[mdkent]

Description

Running dmidecode under Rosetta in a very simple Ubuntu 24.04 container locks up Docker Desktop.

Reproduce

1. While on an M Series Mac, run

   docker run --platform linux/amd64 --privileged -it ubuntu:24.04 \
     /bin/bash -c 'apt-get update && apt-get -y install dmidecode && dmidecode'
   

   This will never return.
2. Any other docker command will timeout and fail with request returned Internal Server Error for API route <snip>
3. The Desktop UI is still running, but attempts to control the containers will see HTTP code 500 errors.

Expected behavior

The command should not hang indefinitely under Rosetta.

The arm64 version of the same image works fine:

docker run --platform linux/arm64 --privileged -it ubuntu:24.04 \
  /bin/bash -c 'apt-get update && apt-get -y install dmidecode && dmidecode'

producing

<snip>
Unpacking dmidecode (3.5-3ubuntu0.1) ...
Setting up dmidecode (3.5-3ubuntu0.1) ...
# dmidecode 3.5
# No SMBIOS nor DMI entry point found, sorry.

It's also worth noting that an older Ubuntu 22.04 release, with an older copy of dmidecode, works fine on amd64:

docker run --platform linux/amd64 --privileged -it ubuntu:22.04 \
  /bin/bash -c 'apt-get update && apt-get -y install dmidecode && dmidecode'

producing

<snip>
Unpacking dmidecode (3.3-3ubuntu0.2) ...
Setting up dmidecode (3.3-3ubuntu0.2) ...
# dmidecode 3.3
Scanning /dev/mem for entry point.
# No SMBIOS nor DMI entry point found, sorry.

Additional Info

I'm having trouble deciding where the problem lies for this one, but it seems like Docker shouldn't be able to 100% lock-up while a guest reads /dev/mem.

I am also encountering the same symptoms, but unsure if it's the very same root cause. Nonetheless, here's my diagnostic-id: D3089024-FCCB-4D9E-AE02-697878568B5D/20241220050254
