Exact reason found and corrected: see bug #539467. The "SATA Link Power" was being turned off, apparently when there was still disk activity waiting. Applying "lucid-proposed" version of pm-utils-powersave-policy (currently at 0.3.1) resolves the issues about stopping completely.
Note that the issues about starting were resolved by using the Broadcom STA rather than B43 driver. I don't know if there is any other link. -- Lucid incompatible with HP Mini 110 BIOS (F.15) https://bugs.launchpad.net/bugs/578868 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
