Nikolaus Schaller" , linux-arm-kernel@lists.infradead.org, Aaro Koskinen Hi. I was able to build linux-5.5 and run it on N900 with no problems. Even WiFi works, mmc0 is in place too. It seems you're doing something wrong. Were you able to build linux-5.1 with your scripts and run it on the phone? I mean the pure linux-5.1 without configs and changes done in https://github.com/maemo-leste/n9xx-linux. BTW, I didn't find STACKPROTECTOR_PER_TASK option to be enabled in omap2plus_defconfig. -- Best regards, Spinal > * Tony Lindgren [200207 16:54]: >> * Merlijn Wajer [200207 16:47]: >> > On 07/02/2020 17:36, Tony Lindgren wrote: >> > > >> > > Looks like there's a regression in general for appended dtb booting >> that >> > > was caused by commit 9f671e58159a ("security: Create "kernel >> hardening" >> > > config area").
