Comment(by skliarie):

 I have an Sandisk 8GB MicroSDHC card that usually works ok, but once I
 start to fill it faster than certain speed, the SDHC locks up hard and
 following error appears in dmesg:

 <6>[ 9479.220000] glamo-mci glamo-mci.0: Error after cmd: 0x4120
 <3>[ 9479.220000] mmcblk0: error -110 sending read/write command, response
 0x0, card status 0x400900

 The kernel is provided by the android-on-freerunner week-2009-44 (cat
 /proc/version):
 Linux version 2.6.29-rc3-mokodev (serdar@…) (gcc version 4.2.1) #1 PREEMPT
 Sat Oct 24 16:06:35 CEST 2009

 Is my problem related to this bug?
 Is there a way to change the kernel glamo_mci.sd_max_clk variable using a
 /sys or /proc entry?
