Problems and workarounds while building octeon kernels

[Andreas Barth <aba@not.so.argh.org>]

Hi,

I tried to build an recent linux 2.6.33-rc something in an unstable
Debian chroot. I had the following issues (plus workarounds / fixes) -
please don't hesitate to ask me if you have further questions.


error:
arch/mips/cavium-octeon/built-in.o: In function `prom_init':
(.init.text+0x974): undefined reference to `early_serial_setup'
arch/mips/cavium-octeon/built-in.o: In function `prom_init':

arch/mips/cavium-octeon/built-in.o: In function `flash_init':

fix: enabled configuration for serial console support

fix: set drivers/mtd to y (instead of m)

arch/mips/cavium-octeon/built-in.o: In function `sched_clock':

workaround: in arch/mips/cavium-octeon/csrc-octeon.c
#if (__GNUC__ < 4) || ((__GNUC__ == 4) && (__GNUC_MINOR__ <= 3))
replaced by something that always uses "the ugly way"


ERROR: "i8253_lock" [drivers/input/misc/pcspkr.ko] undefined!
fix: disable pc speaker support
