Arch linux guest crash after windows 10 host resume from sleep

[lindeshun]

I wrote a topic about this on the virtualbox forum​https://forums.virtualbox.org/viewtopic.php?f=6&t=102250&sid=f398ac48ffa5927918c82d13ef2c7ce8.

Here are how I reproduce the problem:

---

1. start Arch linux guest
2. Windows 10 host sleep
3. resume Windows 10 host
4. Arch linux guest is PAUSED, try to resume it
5. whole virtualbox interface freeze, crash (log "carsh")

---

However, if I pause and resume the guest manually once before the host go to sleep, the probelem is gone.

---

1. start Arch linux guest
2. pause guest and resume it immediately
3. Windows 10 host sleep
4. resume Windows 10 host
5. arch linux guest is RUNNING, everything works fine (log "workfine")

---

Additionally, I also have a windows 10 guest and a ubuntu 16.04 guest, neither of them have this problem.

I made a similar observation: VBoxManage crashes on resume :

• Host Windows 10
• Guest CentOS 8
• Windows 10 host sleep
• resume Windows 10 host
• Guest tells me it's halted and to resume it
• Tried to resume via GUI; but: Virtualbox interface freezes
• Tried to resume via VBoxManage; but it crashes:

Error-Message:
