Platform is x86_64. It happens only when root filesystem is at SDHC card. At 3.14.31-rt28 or recent plain vanilla kernels I haven't spotted this issue. Boot panic is possible to workaround by adding kernel parameter: "scsi_mod.scan=sync", but it still happens during initrd rebuild using update-initramfs at Debian Jessie. Log from panic is attached. Thanks for any comment regarding issue or better way for bug-report, Michal --------------020604060009020200040403 Content-Type: text/plain; charset=windows-1250; name="panic-mmc-3.18.7-rt2.log" Content-Transfer-Encoding: base64 Content-Disposition: attachment;
