Hello Michael, Thank you for the boot logs. The warnings seem very similar to the ones we are seeing, so it is probably the same issue. I am sorry to hear that the patch I sent earlier did not solve your problem. But as a matter of fact, it did not solve our problems completely either. Now that I enabled CONFIG_HIGH_RES_TIMERS the boot hang issue is back. So, the 3.10.10-rt7 kernel boots with CONFIG_ATMEL_TCB_CLKSRC set, but if I also enabled the high resolution timers the boot hangs (I did not change any other setting in menuconfig). The 3.6.9-rt21 kernel works with similar config just fine apart from the two boot warnings. I also did rt-tests with the 3.6.9-rt21 kernel, and I did not find anything abnormal. I have attached boot logs for both the working 3.6.9-rt21 and the broken 3.10.10-rt7 kernels (I removed some unrelated product specific details from log). The 3.10.10-rt7 has the patch I sent earlier applied. I also noticed that when the clock source is changed to tcb_clksrc the printk timestamps are not incremented anymore (see 3.10.10-rt7 bootlog). If anyone has any ideas about what could be causing these issues, I would be happy to hear all the ideas.
