Description Robert de Vries 2005-03-06 19:34:38 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.3; Linux) (KHTML, like Gecko)

Description of problem:
When I manually configure the kernel for my personal setup using the kernel source package with the 8K kernel stack option, I get link errors saying that it cannot find irq_ctx_init().
I have traced this to some weird #ifdef/#ifndef CONFIG_XEN statements in include/asm-i386/irq.h.
The #ifdefs may help in compiling the XEN kernels, but if you configure 8K stacks you can't link normal kernels.
The patch introducing the change is called: linux-2.6.9-xen-compile.patch

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Configure 8K stack with menu config or any config tool
2. Build kernel

Actual Results:  Link failure on missing symbol: irq_ctx_init

Expected Results:  Linked linux kernel

Additional info:

After reverting the part of the patch below, the kernel compiles and links fine.
