Current Issues
After resume from suspend2ram, video playback is "blocky", about an order of magnitude slower than it should be. Refer to https://launchpad.net/bugs/84898
- Occasionally, upon resume, the network "isn't there": Network Manager spins but never connects. Sometimes a suspend-resume cycle corrects this, sometimes not, and a reboot is required. No bug report (yet), because no reliable way to reproduce or track. I'm working on it....
- Occasionally, upon resume, sync with my Palm PDA over serial does not work. Sometimes a suspend-resume cycle corrects this, sometimes not, and a reboot is required. No bug report (yet), because no reliable way to reproduce or track. I'm working on it....
#2 and #3 appear to be unrelated (network can work, serial no; serial can work, network no). Still working on this one.
And not really an issue, but: "BIOS age (1999) fails cutoff (2000), acpi=force is required to enable ACPI". ACPI works fine, this machine should be whitelisted. I added this to a bug report, I'm sure I did, I may create one specific to this machine.
