[-- Attachment #1: Type: text/plain, Size: 6039 bytes --]

I'm announcing the release of the 3.2.28 kernel.

All users of the 3.2 kernel series should upgrade.

The updated 3.2.y git tree can be found at:
        git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-3.2.y
and can be browsed at the normal kernel.org git web browser:
        http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git

Ben.

There are previous reports of these weird rcu_bh stalls with t=0 in the 3.2

Hi, Henrique

rsp->gp_start and rsp->jiffies_stall should already set before we start
check stall for this gp, but the INFO show that we have a current
jiffies which bigger then rsp->jiffies_stall but equal to rsp->gp_start,
really strange...

Could you please have a try on the latest kernel and confirm whether
this issue still exist?

BTW:
	Is this stall info comes from a virtual machine?

Regards,
Michael Wang

It is a production box, it is difficult to run a -rc kernel there.

And the stalls are very rare, too.  That's the only one I got, so at this
point I cannot tell you whether something fixed the problem or not, just try
to give you clues if a stall does happen.

No, it runs on baremetal.  The box has one Xeon X5550 processor, 4 cores, 8
threads, and it is allowed to go into C1, C3 and C6 (which it does very very
often).

It might be some sort of race related to SMIs?  The worst-case SMM-induced
delay on this box is quite high (I don't recall if that means 150ms or
150us), as measured by the Intel BITS[1].

Please note that I can only directly deal with regressions that are
specific to 3.2, caused by a bad backport.  For anything else, you need
to identify an upstream fix to be applied - I'm not usually going to
have the time to do that.

Says it was fixed in (Fedora's) 3.3 - so perhaps there are multiple bugs
involved.
