[Regression] Build failure in current mainline - firmware related

[Rafael J. Wysocki]

Hi,

I get the following error from 'make modules_install' on my test boxes:

  HOSTCC  firmware/ihex2fw                                                             
/home/rafael/src/linux-2.6/firmware/ihex2fw.c:268: fatal error: opening dependency file firmware/.ihex2fw.d: Read-only file system                                            
compilation terminated.                                                                
make[3]: *** [firmware/ihex2fw] Error 1                                                
make[2]: *** [_modinst_post] Error 2                                                   
make[1]: *** [sub-make] Error 2                                                        
make: *** [all] Error 2

where the configuration is that the kernel is compiled on a build box
with 'make O=<destdir> -j5' and then <destdir> is mounted over NFS read-only by
each test box (full path to this directory is the same on the build box and on
the test boxes).  Then, I cd into <destdir>, run 'make modules_install' and get
the error above.

2.6.28 didn't have this problem.

Thanks,
Rafael
