Hello:

When mana_serv_reset() encounters -ETIMEDOUT or -EPROTO from
mana_gd_resume(), it performs a PCI rescan via mana_serv_rescan().

mana_serv_rescan() calls pci_stop_and_remove_bus_device(), which can
invoke the driver's remove path and free the gdma_context associated
with the device. After returning, mana_serv_reset() currently jumps to
the out label and attempts to clear gc->in_service, dereferencing a
freed gdma_context.
