APAR Error Description / Circumvention

-----------------------------------------------
Deadlock between ALT-STACK-TASK, ALT-LLMNR, and IDELANRBOOTP
tasks due to a timing window during initialization of the
service TCP/IP stack during IPL. This prevented the service
TCP/IP stack from starting the LAN adapter, resulting in LAN
console being unavailable. The deadlock may occur only if the
tagged LAN console adapter is different from what was configured
from the previous IPL.

CORRECTION FOR APAR MA47826 :
-----------------------------
During initialization of the service TCP/IP stack in
ALT-STACK-TASK, other operations against the service stack will
be blocked until ALT-STACK-TASK is completely ready to process
them. This will prevent the deadlock and resulting
unavailability of LAN console.

CIRCUMVENTION FOR APAR MA47826 :
--------------------------------
None.
