https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D204521 --- Comment #78 from Gary Jennejohn <gljennjohn@gmail.com> --- I notice that the driver currently limits the SD clock to a maximum of 50MH= z. In the Linux trace the clock is set to 208MHz. I wonder whether the clock rate is contributing to the errors seen when rtsx_xfer() is used. In particular, CMD18 trying to read 8192 bytes in a single transfer may be too fast for the controller/SD card to acheive at a lower clock rate. --=20 You are receiving this mail because: You are the assignee for the bug.=
