RE: [announce] OpenBIOS Forth Kernel V1.0 released

[Gregg C Levine]

Hello (again) from Gregg C Levine
Stefan, it looks as if I was right. The version that's on your site,
does cause an oops, here it is:

I suspect that the module, is causing insmod to have a bad time.
Here's the decoded one:
ksymoops 2.4.9 on i586 2.4.21.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21/ (default)
     -m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol
resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to
find
map, modules, ksyms etc.  ksymoops -h explains the options.

13 warnings issued.  Results may not be reliable.

I don't know what ksymoops means about the last line, but its all
there. Everything is as I last posted regarding the kernel project
program. Other then the peculiar complaint from strip it works. Ron,
if your curious, that's from the latest version of Stefan's /dev/bios
module. Why it compiles, but promptly throws that, is why I'm here. If
you want, I'll switch to any other methods of communicating with
Stefan.
