svm from ubuntu_kvm_unit_tests interrupt with "Unhandled exception 13 #GP at ip 00000000004027e3" on F-intel-5.13

[Po-Hsu Lin]

Failing with Focal Intel 5.13.0-1004.4 on node gonzo

A bit like bug 1934939, but this time it looks like this has passed through more cases than that bug.

[Po-Hsu Lin (cypressyew)]

This issue can be reproduced on the same node gonzo with F-intel 5.13.0-1003.3
Therefore this is not a regression.

[Stefan Bader (smb)]

Also happens with hirsute:linux 5.11.0-38.42 for sru-20210927 on that host (gonzo).
