[User-mode-linux-devel] panic initializing module and thread

[John H. H. <jh...@pr...>]

I've been working on a module that implements a simple SUNRPC server.
Creating a server thread in init_module causes a kernel panic:

Kernel panic: Kernel mode fault at addr 0x518000a0, ip 0x518000a0

The address 0x518000a0 is the starting address of the thread's function,
which is inside the module. Could there be a race between installing a
module and setting up its memory, and starting a thread that uses that
memory? This all works fine on a real machine. I'm using
linux-2.4.0-test7. 

Also, it would be nice if ksyms.c exported block_signals and
unblock_signals. I lifted much of my code from nfsd, and it calls these.
