Description Ed 2005-04-15 16:00:51 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050323 Firefox/1.0.2 Fedora/1.0.2-1.3.1

Description of problem:
If you deselect the kernel hacking/4K stack kernel option when building a kernel it fails with the following error message

arch/i386/kernel/built-in.o(.init.text+0x1a47): In function `init_IRQ':
arch/i386/kernel/i8259.c:429: undefined reference to `irq_ctx_init'
arch/i386/kernel/built-in.o(.init.text+0x1a5e):arch/i386/kernel/i8259.c:429: undefined reference to `irq_ctx_init'
make: *** [.tmp_vmlinux1] Error 1

I demonstrated this by taking the kernel config from /boot and building it successfully. Then I did make xconfig and deselected the 4k stack option and got the above failure.

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

How reproducible:

Steps to Reproduce:
1. see above description

Actual Results:  the error message above

Expected Results:  The kernel should have built correctly or information should have been present during configuration explaining how to avoid the problem

Additional info:

I am aware of your contemptuos dustbin classification in 'bug' 126342. This is clearly a problem redhat have introduced and I have gone to some effort to provide a clear and simple demonstration of *your* problem.

This roblem amtters to me as I have to use 3rd party modem drivers which require larger stacks. The 2.6.11 kernel is unusable by me as I cannot use it in conjunction with these drivers.

Rik, this seems to be caused by something in the Xen patches.
Comment 2 Dave Jones 2005-04-15 17:20:47 EDT
actually, it doesnt, bad grep on my part.
this looks to be broken upstream.

as for modem drivers... you are aware of the slmodem userspace modem stack right ?
