Hi, I've bisected boot failures in next-20151016 down to patches in this branch: On Thu, Oct 15, 2015 at 4:42 AM, Tomeu Vizoso <tomeu.vizoso@collabora.com> wrote: > Tomeu Vizoso (20): > driver core: handle -EPROBE_DEFER from bus_type.match() The machine it happened on was OMAP5UEVM: http://arm-soc.lixom.net/bootlogs/next/next-20151016/omap5uevm-arm-omap2plus_defconfig.html But I've also seen it on tegra2, that one bisected down to: > regulator: core: Probe regulators on demand http://arm-soc.lixom.net/bootlogs/next/next-20151016/seaboard-arm-multi_v7_defconfig.html -Olof -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I don't know how to fix that other than with aliases, but that doesn't solve backwards compatibility. > But I've also seen it on tegra2, that one bisected down to: > >> regulator: core: Probe regulators on demand > > http://arm-soc.lixom.net/bootlogs/next/next-20151016/seaboard-arm-multi_v7_defconfig.html This one you need a rootwait I think. The MMC scanning is not guaranteed to be done before the rootfs mounting AFAIK. There may be other problems, but we can't see them since it panics.

This is where -next fills a great purpose, we can make sure we get those aliases added in before the patches go in. >> But I've also seen it on tegra2, that one bisected down to: >> >>> regulator: core: Probe regulators on demand >> >> http://arm-soc.lixom.net/bootlogs/next/next-20151016/seaboard-arm-multi_v7_defconfig.html > > This one you need a rootwait I think.

Embarrassing, I almost always do this and I'm surprised this machine has been this stable without it. -Olof -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
