Hi Catalin,
My kvm-xfstests [1] VM doesn't boot with kmemleak enabled since commit
c5665868183f ("mm: kmemleak: use the memory pool for early allocations").
There is no console output when running:
$ kvm -boot order=c -net none -machine type=pc,accel=kvm:tcg -cpu host \
-drive file=$ROOTFS,if=virtio,snapshot=on -vga none -nographic \
-smp 2 -m 2048 -serial mon:stdio --kernel $KERNEL \
--append 'root=/dev/vda console=ttyS0,115200'
$ kvm --version
QEMU emulator version 2.11.1(Debian 1:2.11+dfsg-1ubuntu7.19)
Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers
Attached defconfig saved by 'make savedefconfig'.
I tried increasing DEBUG_KMEMLEAK_MEM_POOL_SIZE, which did not help.
I also tried moving kmemleak_init() back to its old location, since this
changes seemed unrelated to the commit. Didn't help either.
Let me know if you have any suggestion how to debug this.
Thanks,
Amir.

This was fixed in 5.4-rc4, see commit 2abd839aa7e6 ("kmemleak: Do not
corrupt the object_list during clean-up").

It probably use a bit more memory than before. Does lower the parameter help? Eventually, It should boot with POOL_SIZE=0, no?

Did not fix my issue.
Still not booting with 5.4-rc6.
Any other suggestions?

Can you pass an earlyprintk=ttyS0,115200 (if that's the correct x86
syntax) on the kernel command line? It may print some early messages
that would help with debugging.

http://lkml.kernel.org/r/20191019114421.GK9698@uranus.lan

but not sure whether it has hit mainline yet.
