* Asus C101P Chromeboot fails to boot with Linux 5.2 @ 2019-07-12 15:00 Alex Dewar 2019-07-12 15:44 ` Emil Renner Berthing 0 siblings, 1 reply; 8+ messages in thread From: Alex Dewar @ 2019-07-12 15:00 UTC (permalink / raw) To: Heiko Stuebner, linux-arm-kernel, linux-rockchip; +Cc: linux-kernel Hi all, Since upgrading to the 5.2 kernel, my Chromebook is failing to boot. The Asus C101P is based on the RK3399 SoC and uses the rk3399-gru-bob device tree. It used to boot with the 5.1 kernel and mostly worked, with the exception of broken suspend and resume. When I try to boot the screen just gets flooded with messages like this: http://users.sussex.ac.uk/~ad374/boot_fail.jpg I'm using Arch Linux ARM's linux-aarch64 package, source here: https://archlinuxarm.org/packages/aarch64/linux-aarch64/files/PKGBUILD Best, Alex _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel ^ permalink raw reply [flat|nested] 8+ messages in thread

You can try booting with audit=0 on the kernel command line to get rid of those messages, so you have a better chance of catching the real issue. (Or conclude that audit is what is broken.) /Emil _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel ^ permalink raw reply [flat|nested] 8+ messages in thread

It just alternates between a flashing cursor and a multicoloured square in the middle of the screen. The system isn't totally unresponsive though. If I press the power button it still shuts down properly. I've just tested it again and confirmed that it does boot with the v5.1.11 kernel.

I tried adding ignore_loglevel, but still just get a blinking cursor. So it's definitely a regression. I can have a go at bisecting this if it would help? Or is there something else we could try first?

I'll try to do a bisect later to find the offending commit though. In related news, it also seems that the sound and wifi drivers aren't working either in 5.2 (although I need to do a bit more testing to confirm the latter).
