Well, in the meantime I ran 'make modules_install V=1' and this is the last thing printed (the previous ones are not really interesting):
make -f /home/rafael/src/linux-2.6/scripts/Makefile.fwinst obj=firmware __fw_modinst gcc -Wp,-MD,firmware/.ihex2fw.d -Ifirmware -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -o firmware/ihex2fw /home/rafael/src/linux-2.6/firmware/ihex2fw.c /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
It fails because of the attempt to compile ihex2fw .
Thanks, Rafael
