Hi, Fedora got report of a panic when I accidentally left debugging enabled on a build https://bugzilla.redhat.com/show_bug.cgi?id=1677438 It looks like a panic from code in CONFIG_FAIL_MMC_REQUEST from the cqhci driver because there isn't a command (high level overview) (gdb) list *(mmc_should_fail_request+0xa) 0x149a is in mmc_should_fail_request (drivers/mmc/core/core.c:98). 93 }; 94 95 if (!data) 96 return; 97 98 if (cmd->error || data->error || 99 !should_fail(&host->fail_mmc_request, data->blksz * data->blocks)) 100 return; 101 102 data->error = data_errors[prandom_u32() % ARRAY_SIZE(data_errors)]; (gdb) (gdb) list *(mmc_cqe_request_done+0x1c) 0x2a6c is in mmc_cqe_request_done (drivers/mmc/core/core.c:505). 500 void mmc_cqe_request_done(struct mmc_host *host, struct mmc_request *mrq) 501 { 502 mmc_should_fail_request(host, mrq); 503 504 /* Flag re-tuning needed on CRC errors */ 505 if ((mrq->cmd && mrq->cmd->error == -EILSEQ) || 506 (mrq->data && mrq->data->error == -EILSEQ)) 507 mmc_retune_needed(host); 508 509 trace_mmc_request_done(host, mrq); (gdb) list *(cqhci_irq+0x1d2) 0x1172 is in cqhci_irq (drivers/mmc/host/cqhci.c:747). 742 data->bytes_xfered = 0; 743 else 744 data->bytes_xfered = data->blksz * data->blocks; 745 } 746 747 mmc_cqe_request_done(mmc, mrq); 748 } 749 750 irqreturn_t cqhci_irq(struct mmc_host *mmc, u32 intmask, int cmd_error, 751 int data_error) This can be worked around by turning off the option but it seems like something to fix up. Thanks, Laura
