Reboot broken on ARM64 virtual servers

[anisse]

Using software reboot on arm64 VPS causes this message to be repeated indefinitely on the serial console:

IRQ Exception at 0x00000000BBC11F38


IRQ Exception at 0x00000000BBC11F38

The only way to restart the server is then to use the API (e.g scw restart) or web interface.

Please tell me if this issue should be moved to another repo.

It's BIOS issue, this is a known issue and their team is working on it... but no ETAs, I have this issue a long time ago.

Same here, instance with IPv4 + IPv6, successfully boot only on every second "reboot":

• Location: Amsterdam,
• Instance type: ARM64-2GB,
• From image: Ubuntu Bionic Beaver

Infinite loop with error message

IRQ Exception at 0x00000000BBC11F38

Another problem, connected with this bug: after instance was created, web-interface shows me that system is available, but it doesn't, because of this bug.

It looks like problem is only for Scaleway's image Ubuntu Bionic Beaver for ARM64.
I tried to use some Debian images (sid and Stretch), they don't have such problem, nor in original state, nor after full upgrade.
Also I tried to use Ubuntu Xenial image and I had only one freeze on soft reboot, but without any message. After that, I updated that Ubuntu 16.04 to 18.04, and again no freezes on reboot.

P.S. With Ubuntu 18.04 upgraded from 16.04 I got on reboot infinity loop with messages:

Synchronous exception at 0x00000000BBC129BC

Bootscript is aarch64 mainline 4.15.11 rev1.

I have the same problem with a debian stretch on an ARM64-2GB in Paris

bootscript is not part of the problem as I changed it to all possible values without any luck

Also having this issue ... At least we know that this problem only happens every other reboot.

But the real issue, is this: what if the server is rebooted without my knowledge? It will get stuck with this IRQ Exception at 0x00000000BBC11F38 until I find my service is not running. Until then, no services on the instance.

Scaleway, please fix this ... ARM64 is a very real opportunity.

Also have this issue on Scaleway. Ubuntu 18.04. Same error message as @eliezedeck

This issue is now 7 months old, has any progress been made? I like ARM, but things like this make the whole server lineup completely useless.

today I facing this issue too.

Same here

I'm getting this as well, this is a serious problem y'all

Just got this message from the support.

However, I understand that you have issues rebooting from within your environment.
This is another issue, caused by the fact that your OS detach volumes when powering off the server.
Since volumes are network-connected, they cannot be re-attached on reboot, and require a hard-reboot from the Scaleway panel to re-attach volume, hence why it does not work.

[abitrolly]

It is not clear why hardware hypervisor can not detect request for reboots and start to handle reboot process itself when it receives this IRQ Exception at 0x00000000BBC11F38.

Same problem here
"IRQ Exception at 0x000000013BC11F38"

[jakolehm]

Same here. Wake up Scaleway.
