Ive tested this on 2 builds differing only by DYNAMIC_DEBUG
It works for me on x86-64

However, I just booted a non-dyndbg build on x86-32, and got this.


root@voyage:~# dmesg | grep Unknown
mac80211: Unknown symbol __dynamic_dev_dbg (err 0)
mac80211: Unknown symbol __dynamic_pr_debug (err 0)
scx200_acb: Unknown symbol __dynamic_dev_dbg (err 0)
scx200_acb: Unknown symbol __dynamic_pr_debug (err 0)
hwmon: Unknown symbol __dynamic_dev_dbg (err 0)
nsc_gpio: Unknown symbol __dynamic_dev_dbg (err 0)
nsc_gpio: Unknown symbol __dynamic_dev_dbg (err 0)
root@voyage:~#

It may be my error, will investigate asap,
but wanted to report now.

thanks
