Re: 2.6.30-rc1 and BeagleBoard: MMC card / Voltage Regulator issues

["Eugeny S. Mints" <eugeny.mints@gmail.com>]

Hi Thomas,

in case it could help:

1) I'm getting the same kernel crash on the latest linux-omap tree

2) you may want to pull omap-2.6.29 if you're looking for somewhat 
stable  - checkout
"Git tree updated, clocks and PM code reset to mainline" thread on this 
list. omap-2.6.29
with default beagleboard config boots fine for me and mounts rootfs on SD.

Thanks,
Eugeny
