Hi
In Debian we got a regression report booting on a Lenovo IdeaPad 1 15ADA7 dropping finally into the initramfs shell after updating from 6.12.30 to 6.12.32 with messages before dropping into the intiramfs shell:
mmc1: mmc_select_hs400 failed, error -110 mmc1: error -110 whilst initialising MMC card
The original report is at https://bugs.debian.org/1107979 and the reporter tested as well kernel up to 6.15.3 which still fails to boot.
Another similar report landed with after the same version update as https://bugs.debian.org/1107979 .
I only see three commits touching drivers/mmc between 6.12.30..6.12.32:
28306c58daf8 ("mmc: sdhci: Disable SD card clock before changing parameters") 38828e0dc771 ("mmc: dw_mmc: add exynos7870 DW MMC support") 67bb2175095e ("mmc: host: Wait for Vdd to settle on card power off")
I have found a potential similar issue reported in ArchLinux at https://bbs.archlinux.org/viewtopic.php?id=306024
I have asked if we can get more information out of the boot, but maybe this regression report already rings bell for you?
Jonathan reported a similar failure regarding to hs400 on RK3399 platform. https://lkml.org/lkml/2025/6/19/145
Maybe you could try to revert : 28306c58daf8 ("mmc: sdhci: Disable SD card clock before changing parameters")
Thanks.
Jeremy, could you test the (unofficial!) packages at https://people.debian.org/~carnil/tmp/linux/1108065/ which consist of 6.12.33-1 with the revert patch applied on top?
I have put a sha256sum file and signed it with my key in the Debian keyring for verification.
