Description
When mounting a remote NFS share you immediatly get into KDL:
nfs: mount(4, <NULL>, 00000000) nfs: nfs_params: nfs:10.138.23.214:/shared,uid=0,gid=0,hostname=haiku nfs:ip! IP:10.138.23.214 nfs:hn! nfs:uid! nfs:gid! nfs: ip:0a8a17d6 server:'10.138.23.214' export:'/shared' hostname:'shredder' uid=0 gid=0 nfs: mountd at d6178a0a:53010 nfs: nfsd at d6178a0a:2049 vm_soft_fault: va 0x0 not covered by area in address space vm_page_fault: vm_soft_fault returned error 'Bad address' on fault at 0x15, ip 0x84b54d93, write 0, user 0, thread 0x8b PANIC: vm_page_fault: unhandled page fault in kernel space at 0x15, ip 0x84b54d93 Welcome to Kernel Debugging Land... Thread 139 "w>Desktop" running on CPU 0
This occurs on a fresh installation of Haiku R30452 (also tested on older builds). The command used to mount was:
mkdir /shared
mount_nfs linux:/shared /shared 0 0
When doing a TCPDUMP on the Server side, the following is sent before crashing:
