recent 8-current panics if load device modules from userspace under vmware

Hi

intsmb0: <Intel PIIX4 SMBUS Interface> port 0x1040-0x104f at device 7.3 on pci0
panic: resource_list_alloc: resource entry is busy

If load modules from startup scripts it panics with such message.

If I add same modules into loader.conf everything goes as expected.
Modules tried: if_le, snd_es137x.

It worked before right, for sure.
I have vmware-specific script to boot my notebook under vmware time-to-time:
$ cat /usr/local/etc/rc.d/011.vmware-setup.sh 
#!/bin/sh

if /usr/local/sbin/vmware-checkvm > /dev/null; then
  echo "vmware configuration"
  ln -sf /etc/X11/xorg.conf.vmware /etc/X11/xorg.conf
  kldstat -q -m if_le || kldload if_le
  kldstat -q -m snd_es137x || kldload snd_es137x
  
  # start in-vm mouse
  /usr/sbin/moused -p /dev/psm0 -t auto &
else
  echo "native configuration"
  ln -sf /etc/X11/xorg.conf.vbook /etc/X11/xorg.conf
fi
