I have the similar problem on my home computer. I have SB600 SATA controller and see "softreset failed" messages during startup. My Ubuntu 9.04 x64 works fine but I have soft-RAID 5 (mdadm) and this raid start recalculation of all checksumms on each reboot. On this moment I just keep my computer online whole day. I will provide technical details later.
I hope this but will be fixed soon. -- Softreset failed (device not ready) https://bugs.launchpad.net/bugs/285392 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
