Subject: Debug level "fixing" crash?
Date: Sat, 7 May 2005 11:57:47 EDT [thread overview]
Message-ID: <ae.71dc49ee.2fae3f7b@aol.com> (raw)
While booting, I was constantly crashing when attempting to mount the JFFS2
filesystem (see below). So, I changed the JFFS2 debugging verbosity from 0 to
2. After doing this, I have not crashed again in numerous tests.
Anyone else seen this kind of behavior and have an explanation?
Thank you.
