That one is the culprit, it is this code in drivers/char/rtc.c. Copied
to Paul Gortmaker who wrote rtc.
static void __exit rtc_exit (void)
{
/* interrupts and maybe timer disabled at this point by rtc_release */
/* FIXME: Maybe??? */
if (rtc_status & RTC_TIMER_ON) {
spin_lock_irq (&rtc_lock); <============
rtc_status &= ~RTC_TIMER_ON;
del_timer(&rtc_irq_timer);
spin_unlock_irq (&rtc_lock); <============
printk(KERN_WARNING "rtc_exit(), and timer still running.\n");
}
Sections marked __exit get discarded when the code is linked into the
kernel, they are kept when the code is a module. But the spin lock
code is kept (in another section) and relocation from .text.lock back
to .text.exit fails. Possible fixes:
Use RTC as a module.
Remove __exit from rtc_exit.
Compile rtc_exit conditional on not being a module.
Remove the spin locks.
