weird pauses during disk access
|Reported by:||stippi||Owned by:||stippi|
It started some time ago, it could be around the time that Marcus last worked on the AHCI driver to add ATAPI support and handle error conditions. The problem could of course be elsewhere, I should revert that particular patch to make sure. Especially shortly after booting, I get these funny "lock-ups". For example, when I move the Terminal window and the icons would need to redraw, the screen would freeze (I can still move the mouse though), and after several seconds, the icons would draw and I could move the window again. Also some applications would have a big delay when starting. The system always continues to work fine after these pauses, they don't seem to have any side effect. Another way to see them is when right clicking the Desktop shortly after boot to mount another partition, the menu would not appear for several seconds. Then everything goes on to work normally again. When I find some time, I will try to roll back the latest changes to the AHCI driver to see if these lock-ups disappear then. Will report back here. Hardware is IBM/Lenovo T60, AHCI driver is used for disk access. Revision is hrev25859, but the problems first appeared sometimes sooner.
