The attached dmesg output from after - USB power loss (affecting mouse and USB stick while USB HD with its own power supply continues to work); - caps lock LED power loss; - no more working Ctrl-Alt-F1-F6 seems no different to me from one generated during a normal boot (attached previously), except for the 2 bottommost lines:

It appears that all USB ports do not supply power anymore. It worked seconds before. kern.log contains: Nov 18 09:54:51 laptop kernel: [15673.436160] ACPI: Waking up from system sleep state S4 ...

USB seems dead. The laptop's two internal touchpad and button-amid-keyboard mice continue to work. Despite the above issues, X seems mostly functional (some apps may hang sooner or later). However, I could not create another session on vt8. Xorg.20.log says: Fatal server error: xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call Suspend to RAM is not affected. The machine is a HP Compaq nc6220 laptop, running Intrepid (updated from Hardy, updated from Gutsy, all release versions, no beta) with the latest updates at the time of writing. Hibernation worked good enough (not perfect, it has other quirks) in Hardy. uname -a: Linux laptop 2.6.27-7-generic #1 SMP Tue Nov 4 19:33:20 UTC 2008 i686 GNU/Linux /proc/version_signature: Ubuntu 2.6.27-7.16-generic -- no more caps-lock LED, Ctrl-Alt-F1-F6 nor USB power some time after boot https://bugs.launchpad.net/bugs/299496 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
