Help logging kernel messages after failed resume

[Gonzalo Nemmi]

OK, it goes like this:

Dell Inspiron 1318, "boot -v" can be found in here: 
http://pastebin.com/f3a1c204a

sysctl -a | grep hw.acpi | sort can be found in here: 
http://pastebin.com/fcfc0035

First shot: Try the "Livefs CD", "myhost# acpiconf -s 3" WORKS !!!
The machine goes into suspend state and 
resumes_from_it_without_any_problems !!

Second shot: Install ... "myhost# acpiconf -s 3" does not work 
anymore ...

I issue a "myhost# acpiconf -s 3" and then I get a kernel 
message: "fwohci0: fwohci_acpi_suspend" ... The machine enters suspend 
state ... so far so good.

Now, when I try yo resume from suspend, the machine spouts a plethora of 
kernel errors .. most notable ones beign "bge0" errors, "fwohci0" 
errors and the following ...:


ad4: WARNING - SETFEATURES SET TRANSFERMODE taskqueue timeout - 
completing request directly
ad4: WARNING - SETFEATURES SET TRANSFERMODE taskqueue timeout - 
completing request directly
ad4: WARNING - SETFEATURES ENABLE RCACHE taskqueue timeout - completing 
request directly
ad4: WARNING - SETFEATURES ENABLE WCACHE taskqueue timeout - completing 
request directly
ad4: WARNING - SET_MULTI taskqueue timeout - completing request directly
ata3: port not implemented
ad4: WARNING - SETFEATURES SET TRANSFERMODE taskqueue timeout - 
completing request directly
ad4: WARNING - SETFEATURES SET TRANSFERMODE taskqueue timeout - 
completing request directly
ad4: WARNING - SETFEATURES ENABLE RCACHE taskqueue timeout - completing 
request directly
ad4: WARNING - SETFEATURES ENABLE WCACHE taskqueue timeout - completing 
request directly
ad4: WARNING - SET_MULTI taskqueue timeout - completing request directly
ad4: TIMEOUT - WRITE_DMA48 retryng (1 retry left) LBA=272675445

As you can tell by now, the machine never recovers from "-s 3" (or 
suspend to ram). 

The thing is, ad4 never gets back to life ... as a consecuence, even if 
the kernel trows its messages to stdout, they never get logged !

Is there a way to record those messages so I can post them on the 
corresponding list and file all the PRs I'm about to file??

Note: I can ssh into the notebook, then "su -" and issue "acpiconf -s 
3", but I can't get the notebook to WOL .. so .. I have to press the 
power button on the notebook to get it to resume and as a consecuence, 
those messages are sent to stdout (notebook screen) and I can't get 
them on the ssh client. SCRIPT(1) it's not a solution either .. because 
ad4 never gets back to life .. so script can't record a thing after it 
went into suspend :( 

Any help will be greatly appreciated.

Just in case you are wondering what happens if I boot with ACPI 
disabled: Fatal trap 9
