Re: resuming from suspend to disk not working with b43

Hi,
Hi,
I know there's an ongoing long thread about suspend in b43, but
the technical level has been above me, and I don't know if anything
there is relevant to me.
When I suspend to disk ('s2disk' from uswsusp), the resume fails if b43
is loaded. The screen stays blank, although I see a cursor flashing.
'modprobe -r b43' before suspending makes the resume work fine, but if I
subsequently load b43 after the resume the machine freezes.
Hm, I use b43 w/ s2disk on a regular basis and it works, but openSUSE has a
userland suspend hook that disables NetworkManager before a suspend.
I am using Debian Sid, b43 from vanilla kernels from kernel.org (2.6.24
isn't in Debian yet). I have had this problem with -rc4 and -rc8. the
only two I've tried. HW is a 4318 Air Force One, in an Acer Aspire
3690-2672. Is there any debugging info I can provide? Is this a known
problem? Is there anything I should try?
Please try to switch off the interface before suspend without unloading the
module.
Also, does s2ram work on your box?

I did 'ifdown eth0' followed by 'ifconfig eth0 down'; I assume that's
what you meant. I do have some sort of HW switch, but I never touch it.
The machine came up okay. 'ifconfig -a' shows eth0 (unconfigured), but
'ifup eth0' and even 'ifconfig eth0 up' returns 'SIOCSIFFLAGS: no such
device. lsmod shows that b43 is still there. When I then did
'modprobe -r b43' followed by 'modprobe b43', the machine froze - no
screen output after the module insertion.
Also, does s2ram work on your box?
I've never gotten it to resume correctly. I tried at one time
many / most of the s2ram option suggestions from the
README.s2ram-whitelist, but nothing worked, and I eventually ran out of
patience for the sort of experimenting that required constant hard
power offs and reboots.

Thanks for the help,

When 2.6.24 is out, please test it, but make sure you don't set
USB_OHCI_HCD_SSB.

There are some suspend debug patches scheduled for 2.6.25 time frame. If they
get merged, we'll be able to check what's going wrong here.
