at least the major kernel version makes sense, because 5.0 had a lot of
changes to this driver. It might be some timing critical issue, which is
triggered by a kernel config change or a change in the mmc core.
Can you please point me to the kernel config of 5.0.17?
Are there any additional changes to the mainline kernel?
There's a few Fedora patches but nothing specific to mmc or the RPi
mmc/sdhci modules.
The patches we had in 5.0.x for RPi was the patch to add support for
the 3A+ and DT improvement series [1]
The ARMv7 and aarch64 configs for 5.0.17 can be found here [2][3] but
our RPi configs didn't change much in the 4.19 - 5.0 range, I think
the most recent one was the addition of CONFIG_BCM2835_POWER when
those changes landed upstream which I think was the 5.1 merge window.
