NFS-related oops in 2.4.5

NFS-related oops in 2.4.5

[Pavel Machek]

Hi!

I got this while compiling kernel over NFS.

pavel@bug:/usr/src/linux-acpi$ time make bzImage
gcc -D__KERNEL__ -I/elf/big/linux-acpi/include -Wall
-Wstrict-prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing
-pipe -mpreferred-stack-boundary=2 -march=i386  -DUTS_MACHINE='"i386"'
-c -o init/version.o init/version.c
gcc: Internal compiler error: program cpp got fatal signal 11
make: *** [init/version.o] Error 1
0.46user 0.23system 6.09 (0m6.092s) elapsed 11.32%CPU
pavel@bug:/usr/src/linux-acpi$

And signal 11 was because:

Retrying compilation, I get exactly same oops.

Rebooted, retried, still same oops. Reboot to 2.4.0 and it works fine.

(Notice that it is not exactly oops, but BUG().)
