I also recompiled with CONFIG_FUSION_LOGGING=y so setting 'mptbase.mpt_debug_level=-1' actually has an effect. But this of course can't be seen when coupled with 'quiet', so the above console output doesn't show this. I'm trying to find a better mpt_debug_level value. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.-- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
