Hi,
I got the following oops in 2.4.18 - output from ksymoops:

Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?

It happens if I do a cat /proc/ioports after a modprobe opl3sa2 io=0x370 mss_io=0x530 mpu_io=0x330 irq=5 dma=0 dma2=1
What to do now? Will upgrading help?
Kind regards,
Brian

Thanks for the bugreport, be sure to CC me for opl3sa2 issues. I can check
further and see where its dying. You can try running the latest -pre or
newer -ac (careful about Alan's *fun* bits though ;) as that has a
slightly updated version. I'm running 2.4.19-pre2-ac3 and can safely cat
/proc/ioports.
Cheers,
Zwane
