Hi everyone,

I've been seeing a lot of this with the debug kernel (2.6.21.1) i'm
using. As far as i can tell, there are no options in the kernel
Makefile that could cause optimizations. Here is a typical call stack
I see:

(gdb) bt
#0 breakpoint () at kernel/kgdb.c:1773
#1 0xc0450298 in kgdb_tasklet_bpt (ing=0) at kernel/kgdb.c:1650
#2 0xc042c119 in tasklet_action (a=********) at
kernel/softirq.c:406
#3 0xc042bcb0 in __do_softirq () at kernel/softirq.c:231
#4 0xc042bd47 in do_softirq () at kernel/softirq.c:268
#5 0xc042bfab in irq_exit () at kernel/softirq.c:304
#6 0xc0406f62 in do_IRQ (regs=********) at arch/
i386/kernel/irq.c:142
#7
#8 mwait_idle_with_hints (eax=0, ecx=0) at arch/i386/kernel/process.c:
251
#9 0xc0403258 in mwait_idle () at arch/i386/kernel/process.c:257
#10 0xc04033a3 in cpu_idle () at arch/i386/kernel/process.c:194
#11 0xc0418d2e in start_secondary (unused=***** out>*****) at arch/i386/kernel/smpboot.c:432
#12 0x00000000 in ?? ()

Notice the with the local variables? I see lots
of those when i try to do an "info locals" at most places too. In the
Makefile, I've removed all -O flags, to no avail.

I'm pasting URLs to my Makefile and .config, maybe you can spot
something.
