Subject: [PATCH] parisc: increase kernel stack size to 32k
Date: Tue, 23 Apr 2013 22:22:03 +0200 [thread overview]
Message-ID: <20130423202203.GA7287@p100.box> (raw)
commit e4e1e78facf7565cada909a69c7fb6415b6e7b83
Author: Helge Deller <deller@gmx.de>
Date: Tue Apr 23 17:19:37 2013 +0200
parisc: increase kernel stack size to 32k
This commit temporarily increases the kernel stack size to 32k to avoid
stack overflows which led to strange and hard-to-debug kernel crashes
all over various kernel components.
The upcoming real fix will implement an own irq stack which should avoid
those crashes without the need for 32k stacks.
