Subject: PXA3xx NAND driver trouble with 'conservative' CPU govenor
Date: Thu, 9 Jul 2009 21:01:37 +0200 [thread overview]
Message-ID: <20090709190137.GW19257@buzzloop.caiaq.de> (raw)
With the cpu govenor set to 'conservative', the PXA3xx NAND driver fails
the tests from drivers/mtd/tests:
sh-3.2# modprobe mtd_torturetest dev=3
[ 386.367730]
[ 386.369296] =================================================
[ 386.375258] mtd_torturetest: Warning: this program is trying to wear out your flash, stop it if this is not wanted.

[ 388.711908] =================================================
modprobe: Failed to load module mtd_torturetest: Bad message.
When setting the govenor to 'performance', the test passes. Has anyone
seen similar issues? Any idea, anyone?
Daniel
