It turns out that this actually regressed some qualcomm modems because
modem-manager started to use some special netlink sockets that were not
enabled in the 5.4 kernel.
To have that we need (see LP: #1998194):
CONFIG_QRTR=m
CONFIG_QRTR_SMD=m
CONFIG_QRTR_TUN=m
CONFIG_QRTR_MHI=m
in the 5.4 kernel
Fibocom L860-GL-16(8086:7560) could cause the ACPI reporting huge
interrupts when modemmanager(1.16.6-2~20.04.1) was started at ThinkPad
X1 Carbon and X13 Yoga. After upgrade to 1.18.6 from proposed channel,
this issue is gone, although this type modem was not supported yet.

So this is a bit of a pickle this SRU. Basically we need to decide on
one of the two worlds: staying compliant with what the manufacturers
demand (not performing the FCC unlock by default) and not breaking users
(as previously modemmanager was automatically performing the unlock). We

Putting a bit more thought into this, I'm a bit concerned by regressing
user. The plus side, as per our face-to-face discussion, there are not
many modem users, but still... maybe I'd like to investigate some
possibilities.
Reading up on the modemmanager page gave me some necessary context here.
