Re: MUSB problem

I'm also seeing this on a variety of kernels, from 2.6.34 to 3.3.0. I must explicitly set musb_hdrc.use_dma=n for the smsc95xx card to function.

MUSB problem
I'm running 3.3.0 on an OMAP DM3730, with SMSC75xx connected via the MUSB device. I get this error continually although the device (and network channel) seem happy: musb_ep_program 835: broken !rx_reinit, ep2 csr a200 What does it mean? How do I fix it (i.e. keep it from happening)? Note: disabling DMA isn't really an option as the whole point of the SMSC75xx is to get gigabit ethernet and I doubt that's possible without DMA :-) Thanks for any pointers/ideas -- Gary Thomas | Consulting for the MLB Associates |Embedded world -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
