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
