It looks as if something that is not tpm_crb added that memory area to iomem_resource because 4.4 driver uses ioremap_nocache() and does not add anything to the resource tree. /Jarkko ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
