Title:
mmc0 error on boot with eMMC CM5
Status in linux-raspi package in Ubuntu:
New
Status in linux-raspi source package in Noble:
Triaged
Bug description:
When attempting to boot the Ubuntu 24.04 image on an eMMC variant of
the CM5, attached to a CM4 I/O carrier board, the boot hangs fairly
early on, just presumably at the point it attempts to mount the "real"
root. The following error message is repeated on the console:
[ 14.648143] mmc0: mmc_select_hs400 failed, error -84
[ 14.653123] mmc0: error -84 whilst initialising MMC card
This occurs with both the noble release kernel (6.8.0-1004.4), and
with an image built from up to date sources using the noble-updates
kernel (6.8.0-1015.17). I haven't managed to test the noble-proposed
kernel (6.8.0-1016.18) yet.
The issue doesn't occur with the oracular image (with kernel
6.11.0-1004.4).
I'll attach the output from the serial console from as far as it got.
