This Bug tracks the necessary backport for the Linux Kernel
to enable proper reset/recovery of PCI Functions in the error state.
There is a related fix to s390-tools but the relevant zpcictl command
is not part of Ubuntu 18.04
Upstream this includes the following commits:
In the Kernel:
17cdec960cf776b20b1fb08c622221babe591d51 s390/pci: Recover handle in
clp_set_pci_fn()
Backport patch attached.
576c75e36c689bec6a940e807bae27291ab0c0de s390/pci: Fix possible deadlock in
recover_store()
applies cleanly but for the second a small backport change is necessary.
These fixes are already in 20.04 but need also be applied to 18.04.
