Kernel build fails "cannot move ‘arch/arm/boot/compressed/.piggy.gzip.o.tmp" then succeeds

[Pavel Machek <pavel@ucw.cz>]

Hi!

Ok, I guess it is second time I see it.

This time it is while cross-compiling 4.0 kernel on 4.4-rc5. Failure
is:

  AS      arch/arm/boot/compressed/piggy.gzip.o
  AS      arch/arm/boot/compressed/piggy.gzip.o
mv: cannot move ‘arch/arm/boot/compressed/.piggy.gzip.o.tmp’ to ‘arch/arm/boot/compressed/.piggy.gzip.o.cmd’: No such file or directory
scripts/Makefile.build:294: recipe for target 'arch/arm/boot/compressed/piggy.gzip.o' failed
make[2]: *** [arch/arm/boot/compressed/piggy.gzip.o] Error 1
arch/arm/boot/Makefile:52: recipe for target 'arch/arm/boot/compressed/vmlinux' failed
make[1]: *** [arch/arm/boot/compressed/vmlinux] Error 2
arch/arm/Makefile:308: recipe for target 'zImage' failed
make: *** [zImage] Error 2
make: *** Waiting for unfinished jobs....

I'm building it like this...

eval ` eldk-switch.sh -r 5.4 armv7a`
ARCH=arm long make -j 3 zImage uImage LOADADDR=0x8000  && \

It builds ok after re-run. Is building zImage and uImage at the same
time bad idea?

pavel@duo:~/stahl/linux$ ./mkit
Setup for armv7a (using ELDK 5.4)

  CALL    scripts/checksyscalls.sh
  CHK     include/generated/compile.h
  CHK     kernel/config_data.h

  Kernel: arch/arm/boot/Image is ready
  Kernel: arch/arm/boot/zImage is ready
  Kernel: arch/arm/boot/zImage is ready
  Image arch/arm/boot/uImage is ready
make took 0 minutes 37 seconds

Any other ideas?

Thanks,
