Hello I am using a BeagleBone Black for some remote data reading purposes.
Every once and a while the device space will completely fill up very rapidly and it seems like the culprit is kern.log (and syslog) getting spammed with the same message: ubuntu@BBB-00946:/var/log$ tail -f kern.log Mar 20 21:36:26 BBB-00946 kernel: [10458038.623874] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723116 Mar 20 21:36:26 BBB-00946 kernel: [10458038.624084] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723115 Mar 20 21:36:26 BBB-00946 kernel: [10458038.624292] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723114 Mar 20 21:36:26 BBB-00946 kernel: [10458038.624672] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723113 Mar 20 21:36:26 BBB-00946 kernel: [10458038.636575] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723112 Mar 20 21:36:26 BBB-00946 kernel: [10458038.659169] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723111 Mar 20 21:36:26 BBB-00946 kernel: [10458038.661684] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723110 Mar 20 21:36:26 BBB-00946 kernel: [10458038.671142] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723109 Mar 20 21:36:26 BBB-00946 kernel: [10458038.672614] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723108 Mar 20 21:36:26 BBB-00946 kernel: [10458038.676891] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723107 Mar 20 21:36:26 BBB-00946 kernel: [10458038.677989] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723106 Mar 20 21:36:26 BBB-00946 kernel: [10458038.683226] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723105 Mar 20 21:36:26 BBB-00946 kernel: [10458038.683726] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723104 Mar 20 21:36:26 BBB-00946 kernel: [10458038.683957] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723103 Mar 20 21:36:26 BBB-00946 kernel: [10458038.684170] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723102 Mar 20 21:36:26 BBB-00946 kernel: [10458038.684557] omap_hsmmc 481d8000.mmc: [omap_hsmmc_pre_dma_transfer] invalid cookie: data->host_cookie 1 host->next_data.cookie -2146723101 ... clearing the log file and rebooting the system fixes the issue at least for awhile but I would like to understand what is happening. Does anybody know where this is coming from and what the best way to deal with it is? some system info ubuntu@BBB-00946:/var/log$ lsb_release -a No LSB modules are available.
