Dear all,
FC5 will not suspend with the lirc_dev module loaded. Looking at
dmesg, I see something like:
----------------------------------------------------8X-----------------------------------------------------------------
lirc_dev: no version for "struct_module" found: kernel tainted.
lirc_dev: IR Remote Control driver registered, at major 61
The bttv_* interface is obsolete and will go away,
please use the new, sysfs based interface instead.
lirc_gpio (-1): card type 0x22, id 0x6606107d
lirc_dev: lirc_register_plugin: sample_rate: 0
lirc_gpio (0): driver registered

I will also submit a bug report to Atrpms but for the time being the
problem can be solved by manually unloading the modules prior to
suspending the machine.
What I would like to know is if there is any place where I can put
scripts to automate the unloading and reloading of such problematic
modules.
TIA
