From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Horman Date: Mon, 26 Oct 2015 03:20:39 +0000 Subject: Possible Regression due to c074fef5d36e ("of/platform: Defer probes of registered devices"). Message-Id: <20151026032039.GA1950@verge.net.au> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-arm-kernel@lists.infradead.org Hi, I have observed a possible regression in next-20151022 due to c074fef5d36e ("of/platform: Defer probes of registered devices"). The problem manifests on the r8a7791 based koelsch board. With the above patch present booting the board using the shmobile_defconfig results in no console output. While after reverting the above patch the boot proceeds all the way to user-space. With DEBUG_LL and EARLY_PRINTK enabled I was able to capture some console output. I have included both that boot log, and a log of boot all the way to userspace with the patch in question reverted. The problem does not seem to manifiest on other boards for other Renesas ARM SoCs that I have access too. In particular the r8a7790 based lager board; the r8a7790 and r8a7791 are both members of the R-Car Gen2 family of SoCs.

Message-ID: <20151026032039.GA1950@verge.net.au> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Hi, I have observed a possible regression in next-20151022 due to c074fef5d36e ("of/platform: Defer probes of registered devices"). The problem manifests on the r8a7791 based koelsch board. With the above patch present booting the board using the shmobile_defconfig results in no console output. While after reverting the above patch the boot proceeds all the way to user-space. With DEBUG_LL and EARLY_PRINTK enabled I was able to capture some console output. I have included both that boot log, and a log of boot all the way to userspace with the patch in question reverted. The problem does not seem to manifiest on other boards for other Renesas ARM SoCs that I have access too. In particular the r8a7790 based lager board; the r8a7790 and r8a7791 are both members of the R-Car Gen2 family of SoCs.
