Subject: Re: 2.5.51: sleep broken

Message-ID: <200212152356.09656.p_christ@hol.gr> (raw)
In-Reply-To: <200212131604.23595.p_christ-U04EIuiosng@public.gmane.org>

I also noted some perculiarity in the code:

in: linux/arch/i386/kernel/acpi.c
in: acpi_reserve_bootmem(void)
...
        if ((&wakeup_end - &wakeup_start) > PAGE_SIZE)
                printk(KERN_CRIT "ACPI: Wakeup code way too big, will crash on 
                      attempt to suspend (0x%8.8lx)\n",
                        (&wakeup_end - &wakeup_start));

--- I added the parameter to see what's happening. The message indicated an 
0x3000 size. (12k)

the comment for the fn says:
 * We allocate a page in low memory for the wakeup
 * routine for when we come back from a sleep state. The
 * runtime allocator allows specification of <16M pages, but not
 * <1M pages.

Are the above lines correct? AFAIK macro PAGE_SIZE = 4096
That would mean that only <4k code is allowed. OK, but the comment suggests 
otherwise...
