Same thing here, getting a hard lock for our devices with the SDHCI controller enabled, sometimes we are lucky to see the following: [ 4.790367] mmc0: SDHCI controller on 84b0000.sdhci [84b0000.sdhci] using ADMA 64-bit [ 25.802351] INFO: rcu_sched detected stalls on CPUs/tasks: [ 25.807871] 1-...: (1 GPs behind) idle=561/140000000000000/0 softirq=728/728 fqs=5252 [ 25.815892] (detected by 0, t=21017 jiffies, g=61, c=60, q=55) [ 25.821834] Task dump for CPU 1: [ 25.825069] kworker/1:1 R running task 0 509 2 0x00000002 [ 25.832164] Workqueue: events_freezable mmc_rescan [ 25.836974] Backtrace: [ 25.839440] [] (0xce32fea4) from [] (0xce32fed4) [ 25.845803] Backtrace aborted due to bad frame pointer Also confirmed that reverting that change ("mmc: sdhci: Fix voltage switch delay") allows devices to boot properly. Had not a chance to test the change when submitted for mainline despite being copied, sorry about that. Since that specific commit is also included in the other stable trees (5.4, 5.10, 5.15 and 6.0) I will let you know whether the same issue is present in those trees shortly thereafter. -- Florian
