Re: Fwd: [Suspend-devel] resume not working on acer ferrari 4005 with radeonfb enabled

Hello,
yes, it resumes OK, when I don't have radeonfb and pass kernel options: irqpoll acpi_irq_balance noapic (found that on the gentoo acer ferrari wiki here: http://gentoo-wiki.com/HARDWARE_Gentoo_Acer_Ferrari_4005WLMi_Manual
(maybe these issues should be reported to some kernel developers as well)

I use a patched dsdt but I cant remember where I got it from. I uploaded it to: http://christianhoffmann.de/temp/dsdt2.dsl

Yes, I use the free radeon xorg driver at the same time and X is running when suspending. Ill try without.

I dont know how to get more traces than from dmesg and /var/log/messages. Seems that the kernel params are not shown.

There are many possible reasons for that. The most likely is that the
BIOS isn't bringing the chip back on resume, causing radeonfb to
crash when trying to access it.

I have the same laptop, and it also crashes for me on resume when 
radeonfb is loaded.  However, it also crashes on a resume when radeonfb 
*isn't* loaded, so I hardly considered that a regression.  :)

when I have radeonfb enabled, my laptop (X700 ati mobility) doesnt resume
anymore. Screen stays black and nothing works anymore, no capslock light, no
ctrl alt sysreq b etc. I tried all kind of things vbetool, passing
acpi_sleep=s3_bios,s3_mode to the kernel. Nothing seems to work.

...but it used to work?  Now that's interesting; this is the first 
report I've heard of a suspend-to-RAM (and subsequent resumes) working 
on that machine.

You can see dmesg output and lspci -vv output here 
 http://christianhoffmann.de/temp/radeon.log
 http://christianhoffmann.de/temp/lspci.log

Can you send the *full* bootup log, including the command lines you 
used?

I noticed that you have the 'radeon' drm module loading too; that may be 
causing problems.  Are you running X when you try to suspend/resume?

Also, since you're using a Ferarri 4000, are you using the stock 3A23 
BIOS/DSDT, or are you using the patched DSDT from http://acpi.sf.net?
