Reproducible panic in 4.99.72

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

I'm trying to update my O2's userland but whenever I try to untar  
base.tgz I immediately get a panic from gzip. The kernel has WAPBL  
support, sources are from half an hour ago.

10 finger copy:
trap: TLB miss ( load or instr. fetch )
status=0xff03 cause=0x08 vaddr=0x30
uvm_load
pipe_write
dowritefile
sys_write
syscall_plain
mips3_SystemCall

vaddr=0x30 sounds like a NULL deref.

Any ideas?

have fun
Michael
