'fatal: Out of memory? mmap failed: No such device' using cifs

Hi,

I got : 'fatal: Out of memory? mmap failed: No such device' when doing
'git init' in a directory on a mounted cifs share. Any ideas?

I'm using cifs with autofs, here's what I use :
win1
-fstype=smbfs,rw,credentials=/etc/smb.auth,gid=admin,file_mode=0777,dir_mode=0777,nocase,directio,sfu,iocharset=utf8
        ://10.1.1.8/DATA/

git version 1.7.8.2
2.6.32-37-generic-pae

$ mount
//10.1.1.8/DATA/ on /net/smb/win1 type cifs (rw,mand)

Thanks,

Bruno
