Hi,


I cloned master a few days ago and when I boot up the OMAP3 LDP, the board seem to hang in the "i2c /dev entries driver" dialog and after a minute the kernel dumps. Have anybody else seen this problem?

Log is below.

Best regards,
 Mikkel

LDP was broken in .29 as well, at least for mmc: http://patchwork.kernel.org/patch/15340/

Hi,

On 2.6.29 I can use NFS and the board will boot my file system. On the 2.6.30-rc 2 the board is not even coming this far.

Best regards,
Mikkel

 I found that the commit "92f00c2fa10629bad7206cd613d3b3357c8d6a81 - Extra omap code in linux-omap tree" breaks the LDP bootup.

Best regards,
 Mikkel
