Can you please check if this fixes the similar issue on Magnus' ALT? My (old, latest is v4.15) logs show the same timeout, but with errors 84 (EILSEQ) or 110 (ETIMEDOUT) instead of 5 (EIO). Thanks!

[PATCH v2 0/3] mmc: tmio: Fix reset operation
From: Niklas Söderlund Hi, While looking at the Renesas BSP kernel I found patches which improves the state of the hardware at probe and after runtime resume. Patch 1/3 make sure the module clock is enabled after resuming before register are accessed. Patch 2/3 is the real change in this series and brings in reset of the vendor specific callback when resetting (SCC in the Renesas case). While 3/3 simply make sure that the IRQ mask for Renesas boards (Gen2 and later) are in a good shape after probe (and reset). In addition to addressing the state after resuming it helped unbreak a SD card I have which are very problematic on Koelsch. Without this series inserting the card results in: sh_mobile_sdhi ee10.sd: timeout waiting for hardware interrupt (CMD19) sh_mobile_sdhi ee10.sd: timeout waiting for hardware interrupt (CMD19) sh_mobile_sdhi ee10.sd: timeout waiting for hardware interrupt (CMD19) sh_mobile_sdhi ee10.sd: timeout waiting for hardware interrupt (CMD19) sh_mobile_sdhi ee10.sd: timeout waiting for hardware interrupt (CMD19) sh_mobile_sdhi ee10.sd: timeout waiting for hardware interrupt (CMD19) sh_mobile_sdhi ee10.sd: timeout waiting for hardware interrupt (CMD19) sh_mobile_sdhi ee10.sd: timeout waiting for hardware interrupt (CMD19) sh_mobile_sdhi ee10.sd: timeout waiting for hardware interrupt (CMD19) sh_mobile_sdhi ee10.sd: timeout waiting for hardware interrupt (CMD19) sh_mobile_sdhi ee10.sd: Tuning procedure failed mmc0: tuning execution failed: -5 mmc0: error -5 whilst initialising SD card sh_mobile_sdhi ee10.sd: timeout waiting for hardware interrupt (CMD19) While with this series applied (patch 2/3): sh_mobile_sdhi ee10.sd: timeout waiting for hardware interrupt (CMD19) mmc0: new ultra high speed SDR50 SDHC card at address mmcblk0: mmc0: SU04G 3.69 GiB mmcblk0: p1 p2 Patch 1/3 was previously part of 2/3 but as it deals with a unrelated issue it's here broken out to a separate patch. Patch 3/3 have once been posted outside this series bit after comments from Wolfram it's brought back as it now deepens on 2/3. Most changes in this series are based on similar work from Masaharu Hayakawa but for this version all changes now differ quiet a lot from his work. All mails sent to him bounce with a "Undelivered Mail Returned to Sender" error. I therefor felt the need to claim authorship as I don't want to post blame of my (potential) mistakes on some else.
