Hi,
I compiled a kernel which otherwise runs fine, but crashes hard during 
the ftp transfers from my qube.
I am trying to debug this problem and accordng to FAQ, I build kernel 
with makeoptions=-g, crashed the kernel to obtain a core dump and now I 
am running in to a problem.

FAQ states that I need to do "target kcore" command in the gdb but gdb 
does not have a kcore target and "target core" complains about the file 
format. How do I debug this sort of crash?

The only thing I can tell so far that it is a TLB miss on load or 
instruction fetch in the kernel mode. It is caused by ftpd.
I compiled somewhat reduced kernel but why should it crash during ftp 
transfer?

I have not noticed anything strange during any other operation, only 
ftpd transfering data out.

Thanks,
Alex
