It's a duplicate of 16334. Or rather 16334 is a duplicate of this
but the discussion about the issue was more developped in 16334.
Anyway this is not a regression (at least not recent) and the fix
from Al is in the vfs tree in the for-next branch on commit
6c2bdaf089a3876226893fab00dd83596c465ad2
"Fix reiserfs_file_release()"
Thanks.

Since it's a reproducible deadlock maybe the fix should go upstream faster
than v2.6.36?
Thanks,

Thanks for the update, but I'm not really sure if r8169 is involved.
It seems that cpuidle is the source of the warning.

May be yeah. Although the fix is not a naive trick and it changes a sensitive
piece of code.
Don't know what Al has planned with it.

As far as I know, it's only a lockdep warning, not an actual deadlock.
And it's in a class of lockdep warnings that we've had for a long
time, and has never actually triggered as a read deadlock afaik.
I also don't think it's a new warning - or at least I don't see why it
would have started triggering after 2.6.34.
My preferred fix in many ways would be to make the locking in the VM
layer less incestuous. For example, we could fairly easily move the
final
if (vma->vm_file)
fput(vma->vm_file);
outside the actual mmap_sem lock (well, "fairly easily" here means
keeping the list of free'd vmas around for longer, probably in the
task_struct thing, and then replacing all the
"up_write(&mm->mmap_sem)" things with a "unlock_mm(mm)" looking
something like
static void unlock_mm(struct mm_struct *mm)
{
struct vm_area_struct *vma_list = current->vma_to_free;
if (vma_list)
current->vma_to_free = NULL;
up_write(&mm->mmap_sem);
while (vma_list) {
struct vm_area_struct *vma = vma_list;
vma_list = vma_list->next;
fput(vma_list->vm_file);
kmem_cache_free(vm_area_cachep, vma);
}
}
which would fairly trivially delay the actual 'fput()' to after we
hold no locks.
I dunno if it's really worth it, but it doesn't look all that
complicated, and it would avoid at least _some_ lock dependencies.

Two commits in the X server repo (1.8 branch commits shown) might help
here:
commit 665aa7ce8645b50b888db32ebab4e192dbe00649
OS support: fix writeable client vs IgnoreClient behavior
commit 090d26723f7cdbb3aebfe212170b7f81c163dd7b
dixstruct: make ignoreCount change more ABI friendly
2.6.34 introduced some new features, and X will test for them and use
them if available. However, the server's handling of clients was buggy
with the new code, which could cause clients to hang after VT switch,
waiting to be woken up.

If if matters, I saw such messages in the server log when the hang
happened:
[mi] EQ overflowing. The server is probably stuck in an infinite loop.
