Hi, The kernel stalls very early in the boot process. Nothing's even printed to the console with earlyprintk. This can be reproduced using qemu: $ ARCH=x86 make i386_defconfig $ ARCH=x86 make menuconfig # And select preempt rt full $ ARCH=x86 make all $ qemu-system-i386 -kernel arch/x86/boot/bzImage I've tried the same with 4.18-rt and an earlier version of 4.19-rt. The kernel boots on 4.18-rt, but not any version of 4.19-rt. It also boots fine if I use the default scheduling method. Has someone run into the same issue? Best regards, Andri
