Hi, Some weeks ago I installed Testing on my wife's iMac [1] from 2008. Unfortunately it has one issue:
There are irregular periods of very high %wa, maybe 3-5 times per hour, not directly related to a certain user action. They last for some seconds up to even a minute or so and render the machine unusable for that time. top shows %wa of 80 or 90%, load can go up to 9 on this dual core machine, iotop shows only a few KB/s. I already added pcie_aspm=off to the boot options which seems to help, but I still see this I/O hangs (without, I had about 10+ hangs per hour). Any idea what could cause these blockings? How can I find out more? I use Linux for 15+ years but I never saw such things... and I want to show my wife, that Linux is the better OS, of course... ;-) Aside from that issue everything runs quite nicely. Thanks & best regards, Bernd [1] iMac 8,1: 2008, Core 2 Duo 2.8 GHz, GB RAM, 500 GB WD HDD, ATI Radeon HD 2600 PRO (PCIe) -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
