Re: do_softirq solution pending?

Hi,

we are aware that DriverLoader 2.40 does not work on a 2.6.24.x kernel 
because the "do_softirq" symbol is no longer exported to modules. This 
issue is difficult to solve in DriverLoader but our developers are 
working on this.

Patching the kernel to export the symbol, like you did Bob, is probably 
the most straightforward workaround at the moment but should only be 
attempted by users which know what they are doing.

Patching the kernel is not an ideal solution, hopefully something can be 
done in DriverLoader itself to solve this problem.
