Module b44 needs to be blacklisted for hibernate
Last modified: 2008-02-07 14:28:13 EST
Description of problem:
Without blacklisting b44 modules, thaw hangs on Dell Inspiron 6400.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
This used to work in FC6.
Blacklisting the module works around the problem. Suspend doesn't work correctly
on this notebook (machine in painfully slow on resume), so I'm not using that at
Reassigning to pm-utils.
i checked it on f8 with kernel-22.214.171.124-63.fc8, and it seems kernel bug. with
b44 blacklisted everything is ok. with b44 loaded resume from suspend/hibernate
hang with black screen and no error messages
i tried kernel-2.6.24-0.73.rc4.git1.fc9. with this kernel my notebook HP nx6310
trying to resume from hibernate, but something goes wrong and it hangs :(
I don't know how to debug this problem
[timon@localhost ~]$ cat /etc/pm/config.d/unload_modules
SUSPEND_MODULES="kvm_intel kvm iwl3945 b44"
this works for me
Imho the module should be fixed to make it work with hibernate, this needs to be
done in the kernel.
This is wireless so re-assigning as per:
It might also be worth testing with a rawhide kernel if you are able - as far as
I understand it this driver is still undergoing heavy development.
b44 is not wireless -- FYI
Still, it would probably come to me anyway. So, I'll see what I can do...

[TG3]: Fix suspend/resume problem.
in that case a reload of the tg3 driver fixed all problems.
Maybe some ssb bus wrangling is needed in this case....
it seems this bug was fixed in 2.6.24, because fc8 with 2.6.24-2.fc9 kernel
suspend/hibernate and resume fine
