Hi,
I found out that mutt when running with a 2.6.16-rcX kernel is unable to
discover new mails in mboxes other than the main one.
On my system mail is downloaded using fetchmail, which hands the mails
to procmail; procmail then saves the mails in the correct mbox (for
example each mailing list has its own mbox). Using mutt, the 'c' key is
used to changed mbox and it defaults to the first mbox that has new
mail. With kernel 2.6.16 'c' has no effects (mutt seems to think that
there's no new mail).
I think that the problem is related to the changes in:
fs/xfs/linux-2.6/xfs_iops.c
I've done a simple test with working and non working system:
* With kernel 2.6.16-rc2

Note that with 2.6.15 the atime of the mbox is unchanged after opening
mutt, while with 2.6.16-rc2 it does change (I guess that's what confuses
mutt).
Also, looking at strace mutt reads the mbox (so atime changes) but
immediatly resets atime using utime:

Indeed, there have been some atime related changes recently.

Thanks for the details, I should be able to reproduce and fix it
from that - I'll get back to you soon.
cheers.

I constructed a test case based on your description, and this patch
fixes it for me - could you try it out & let me know how it goes in
yoour case?
thanks.
