Definitely not related to i2c.
Apparently the messages are coming from drivers/mtd/chips/gen_probe.c.
So I doubt it is related to networking either...
They are debugging messages, but printk(KERN_DEBUG ...) is used where
pr_debug(...) should be. The following (untested) patch should fix it:
Subject: [MTD] No debug message when debugging is disabled
Use pr_debug(...) instead of printk(KERN_DEBUG ...) so that the message
is only printed when debugging is enabled.
