Hi,

I'm using the pure Hammer bootloader.

At first it worked, but now, after using the system for a while I 
cannot load modules at boot time anymore. So I always have to disable 
acpi, otherwise it will hang shortly after showing some progress 
trying to load the module (it just shows a few "/", "|", backslash, 
"-" characters, then it hangs).
can you ctrl-alt-del the machine at that point or is it locked?
Yes that works.

The kernel itself boots just fine. I am using the GENERIC kernel.
I'm not sure how to debug this...  If your file system is small enough, 
you could put it up somewhere for me to have a look.  Alternatively you 
can build a standalone hammer reader from the boot source in 
lib/libstand/hammerread.c and try to debug why it can't load the 
modules.  I guess it has something to do with the btree layout.
I have problems compiling hammerread:

  cd lib/libstand
  make -DTESTING -DDEBUG=3 hammerread
/usr/libexec/binutils217/elf/ld: errno: TLS definition in 
/usr/lib/libc.so section .tbss mismatches non-TLS reference in 
/tmp//ccVzucFt.o
/usr/lib/libc.so: could not read symbols: Bad value

What am I doing wrong?

Regards,

  Michael
