I can verify that I get the same behavior on a Vaio VGN-S5XP with a an Intel Corporation 82801FBM SATA controller and a FUJITSU MHV2100BH 100GB disk. On the latest Jaunty kernel (2.6.28-11-generic), after a resume disk performance completely deteriorates.
The sar utility reports excessive iowait use between 70% and 90%. I have reverted to kernel 2.6.27-14-generic, where resume works as expected. -- Slow sata disk with ahci driver after resume on Ubuntu Jaunty https://bugs.launchpad.net/bugs/371212 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
