2.6.37-rc7: no more shutdown on DELL E6400

[Eric Valette]

I have the following messages:

Will now halt
hub:4-0:1.0: hub_port_status_failed (err 110)

repeated twice.

I did not attend the shutdown last evening and it was blocked there this 
morning. Retested and found same error.

Will open a regression bug (never have got this since 2.6.33).

Note that after making
	make O=buildir mrproper; make mproper and rebuilding

I still have the hang after the "Will now halt", but no more the usb 
message.

OK, thanks for the info.

Can you update  https://bugzilla.kernel.org/show_bug.cgi?id=25522

to include kernel log messages when you try to shutdown, please?

I'm afraid I cannot. It's my professional computer and I'm now on 
vacation up to January. I will try to see if I have the same problem on 
my home computers.

Besides, at this point (System will now halt) I'm not sure I can do 
anything via keyboard or even gdb remote.

That error message probably has no connection with whatever caused the 
system to hang up.

I've got an E6400 myself and the only time I could get
it to hang was when trying to use brcm80211 driver from
staging. The problem appears when I rmmod/modprobe the
driver after it looses connection to my wifi router.

Since the driver is still in staging and buggy as hell
I didn't bother notifying anyone. But it's true that
shutdown truly hangs.

Are you using brcm80211 driver too ?

No. Mine has an Intel WiFi chipset. With DELL the same reference can be 
used for multiple different hardware instantiation (I have a nvidia vido 
chipset some seems now to have an intel one).

PS: For me the hang appeared with 2.6.37-rc7. I run linux on it for more 
than a year changing stable kernel as soon as they appear and usually 
trying future kernel around rc6 stage.

2.6.36.2 works perfectly. I did not change my config except maybe if the 
make oldconfig was proposing something obvious (e.g new generic MII 
support).

Just as a data point, my Dell E6400 still shuts down fine in both 2.6.37-rc7
 and -rc7-git2. This one has integrated Intel video (i915) and I use the
 out-of-tree broadcom-sta driver for the wireless interface. If needed, I can
 post my .config in the bugzilla entry (but won't, unless asked - in order to
 avoid possible bug noise).

That illustrates if needed the DELL reference multiple hardware problem. I put 
2.6.37-rc7 (git1/git2) on my personnal laptop and I do not experience the 
shutdown problem either.

I hope the problem is rare enough as I cannot supply more information before 
getting back to work.
