Re: [PULL 13/25] hcd-ohci: Fix inconsistency when resetting ohci root hubs

Hi,

This commit breaks boot-serial-test on ppc64-softmmu.

  $ ./configure --enable-tcg-interpreter
'--target-list=aarch64-softmmu alpha-softmmu arm-softmmu hppa-softmmu
m68k-softmmu microblaze-softmmu ppc64-softmmu s390x-softmmu
x86_64-softmmu'
  $ make && cd build && QTEST_QEMU_BINARY=./qemu-system-ppc64
./tests/qtest/boot-serial-test; cd -

(Yes, the full --target-list is needed because boot-serial-test isn't
built when only ppc64-softmmu is selected.)

Here is the CI failure:
https://gitlab.com/qemu-project/qemu/-/jobs/3087540972#L22

 I reproduced this failure and got "Out of malloc memory" error message in the [openbios-ppc](https://github.com/openbios/openbios/blob/4a0041107b8ef77e0e8337bfcb5f8078887261a7/libopenbios/ofmem_common.c#L134). However, I'm not sure how to debug this. Have you run into this issue before?

Best,

Qiang
