Bug#623535: linux-image-2.6.32-5-686: hibernation crash related to ttyACM on Dell 5550 HSPA card

In further testing:
* I have managed to reproduce the crash once without
touching /dev/ttyACM* or the related /dev/cdc-wdm*. That doesn't
rule out those drivers of course as they will run code during
hibernate/restore.
* I got another kernel oops, this time showing a stack trace related
to uhci_hcd (although I guess it's probably one of the individual
device drivers which is causing the trouble).
* However, I seem to have found a workaround: unload these modules
uhci-hcd cdc_acm cdc_wdm dell_laptop dcdbas tg3 brcm80211
by putting
SUSPEND_MODULES='uhci-hcd cdc_acm cdc_wdm dell_laptop dcdbas tg3 brcm80211'
in /etc/pm/config.d/local.
This has at the very least dramatically reduced the failure
probability. (Having kept a systematic record I now see that I
have had 3 out of 3 successful hibernate/resume cycles with these
modules being unloaded, compared to 1 out of 3 today without.
I will report again if I get another failure.)
I'd be happy to carry out experiments if you'd like to suggest any.
Ian.
