Hello, I today pulled linux-omap 2.6.30-rc1 and compiled it to be used on my BeagleBoard. When booting the system I get the trace attached below. If I remove the voltage regulator settings fomr my kernel config, the kernel panic goes away but the system is unable to finde and mount the SD card where my root filesystem is located on. I'm not sure what to do about this and would appreciate any hints. Thanks, Thomas Uncompressing Linux................................................................................................................ done, booting the kernel.
