Hello All !
When I'm trying to compile linux-2.6.8.1 kernel on ppc with kgdb support it
fails with the following error:
arch/ppc/kernel/ppc-stub.c:796: structure has no member named `dbcr0'
Can I just replace regs->dbcr0 with current->thread.dbcr0. Is it sufficient ?
Has this issue already been fixed by someone ?

No, it's not sufficient. It helps to check the archives first.

These are now in the 2.6 mainline (BK current).

I've tried this patch but it fails to apply (at least to 2.6.8.1 from
kernel.org). Am I to use another kernel version to apply this patch ?

The patch is against the current 2.6 BK tree, try patching a recent kernel
release like 2.6.10-rc1.

I've tried 2.6.10-rc1-bk13 from kernel.org. Is it already include this patch ?
It successfully compiles, but at breakpoint() it fails to connect to host's
gdb. I've grab /dev/ttyS1 traffic and see that kgdb stub sends to host a lot
of zeros - nothing more. May be this is bug in serial port initialization ?
How can I deal with it ?

Check what your firmware sets the default baud rate to on the second
UART. I had to set remotebaud 57600 on walnut, IIRC...I'm a little
hazy since that's not my primary devel platform. I think you are
on a different board anyway.
