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?
use cc:

cc -DTESTING -DDEBUG=3 hammerread.c
hammerread /dev/ad0s1a /boot/modules

It hits the right boundary ("hit right boundary (52), resetting search 
to"), and goes into an infinite loop.

Regards,

  Michael
