[Adeos-main] [PATCH] Improve ipipe's oops detection

[Jan Kiszka <jan.kiszka@domain.hid>]

Due to my extended context checks, oopses will first trigger such errors
now before the actual reason is dumped. Patch below ensures that ongoing
oopses disable the context check, and it also pushes the panic-freeze to
a slightly bit earlier point.
