Subject: [2.6.14.5] iounmap: bad address
Date: Thu, 29 Dec 2005 12:04:35 +0100 [thread overview]
Message-ID: <43B3C2C3.1070201@labri.fr> (raw)
Hi,
I am running a 2.6.14.5 on a Transmeta Crusoe laptop (Vaio PCG-C1MZ) and
I'm having some troubles with the iounmap function. Each time I'm
shutting down the machine or even just stopping the gdm daemon, I got
the following error log:
iounmap: bad address d7233000
[iounmap+197/208] iounmap+0xc5/0xd0
[page_remove_rmap+59/96] page_remove_rmap+0x3b/0x60

[drm_release+1010/1232] drm_release+0x3f2/0x4d0
[__handle_mm_fault+447/464] __handle_mm_fault+0x1bf/0x1d0
[__fput+176/400] __fput+0xb0/0x190
[filp_close+82/144] filp_close+0x52/0x90
[sys_close+124/128] sys_close+0x7c/0x80
[syscall_call+7/11] syscall_call+0x7/0xb
I guess the problem is located in arch/i386/mm/ioremap.c where:
write_lock(&vmlist_lock);
p = __remove_vm_area((void *)(PAGE_MASK & (unsigned long __force)addr));
if (!p) {
printk(KERN_WARNING "iounmap: bad address %p\n", addr);
dump_stack();
goto out_unlock;
}
So, it seems that remove_vm_area is returning NULL, and I don't know
why... :-/
Can somebody help me out ?
Regards
