The day has finally come, my laptop finally suspends and resumes correctly under Fedora Core 6 – it’s mostly got part way through the suspend operation before and then hung, or on the few occasions where it shutdown, it would hang or panic on resume.
Today using kernel 2.6.19-1.2911.6.5.fc6 it worked – suspend all the way to power off, and on resume even got the WiFi fired back up. The only one minor thing it didn’t quite pull off was getting the attached usb hard drive back in action – a quick unplug and replug later and it’s sorted.
This is quite cool, however I’m just in the middle of downloading another kernel update and I hope that keeps the progress made with suspend and resume on this laptop.
Just to confirm, suspend / resume works on the next kernel too (2.6.20-1.2925.fc6)
Congratulations! I never succeeded in getting my Acer Ferrari 4005WLMi to resume properly with FC6. Can you please provide more details what you actually did to make it work? Which parameters did you boot the kernel with? Did you have to make any changes in the files located in /etc/pm/? Which BIOS version are you using? Anything else?
Using no kernel parameters on x86_64 FC6 – just “kernel /vmlinuz-2.6.20-1.2933.fc6 ro root=LABEL=/ rhgb quiet”
And standard pm-utils-0.19-3.x86_64 rpm
I’ve found the recent kernels best without the all the other params that are discussed elsewhere on the net (noapic irqpoll acpi_irq_balance etc.) see http://blog.co-comp.co.uk/archives/2-Kernel-Parameters-after-FC4-to-FC5-upgrade-via-yum-on-an-Acer-Ferrari-4005WLMi.html for more detail
Thanks for the information! It made me think why my 4005WLMi and newer 6465WLMi would not resume from suspend. I figured it out on the 6465 and is actually quite simple: disable all modules that you do not need by adding them to /etc/modprobe.d/blacklist with “blacklist module_name”. Add the ones that still insist on loading at boot to /etc/modprobe.conf with “alias module_name off”. Even with the proprietary ATI driver suspend/resume now works like a charm. Hope this helps others that may encounter this problem.
