Public bug reported:
On the NVIDIA (Tegra) Jetson AGX Xavier device running hirsute with any
v5.11 kernel (5.11.0-13.14) the system intermittently gets the following
"mmc0: Timeout" and then hangs. This generally occurs within 24 hours
of uptime:
[25610.386873] mmc0: Timeout waiting for hardware interrupt.

The error and hang can be induced on demand by running this command line twice:
$ sudo cat /sys/kernel/debug/mmc0/mmc0:0001/ext_csd
The first access of 'ext_csd' yields "mmc0: ADMA error: 0x02000000" and a dump,
then the second access yields the timeout and hang.
All of that can be reproduced in mainline as well.
