Try to restore the value for the cache flush timeout, by updating the define MMC_CACHE_FLUSH_TIMEOUT_MS to 10 * 60 * 1000".
I have increased the timeout to 10 minutes but it did not help. Same error found. [ 608.679353] mmc1: Card stuck being busy! mmc_poll_for_busy [ 608.684964] mmc1: cache flush error -110 [ 608.689005] blk_update_request: I/O error, dev mmcblk1, sector 4302400 op 0x1:(WRITE) flags 0x20800 phys_seg 1 prio class 0
OTOH, What best i could do for my own experiment to revert all three patches and now the reported error gone and device mount successfully [1].
List of patches reverted, mmc: core: Specify timeouts for BKOPS and CACHE_FLUSH for eMMC mmc: block: Use generic_cmd6_time when modifying INAND_CMD38_ARG_EXT_CSD mmc: core: Default to generic_cmd6_time as timeout in __mmc_switch()

Thanks for testing!
This sounds a bit weird, I must say. Also, while looking into the logs, it seems like you are comparing a v5.5 kernel with v5.6-rc2, but maybe I didn't read the logs carefully enough.
In any case, I am looking into creating a debug patch so we can narrow down the problem a bit further.
Kind regards Uffe
