The symptoms after resuming are wireless is broken, battery monitoring/management not functioning, and any subsequent shutdown of the Ultrabook can not be done via Software, but must be done by holding down the hardware power switch for 1/2-dozen seconds. This bug does not occur when operating with AC power, but only occurs when running on battery. This anomaly is documented impacting all GNU/Linux distributions in the Z930 linlap page: http://www.linlap.com/toshiba_portege_z930 . This is likely an issue specific to the Toshiba Z930 ACPI implementation. There is also an upstream ACPICA patch (kernel fix) for the anomaly reported here: https://github.com/acpica/acpica/commit/34f226fa2643f1d2e6527ea4edb24947cfe1... Reproducible: Always Steps to Reproduce: 1. allow Ultrabook to suspend when operating on battery power 2. 3. Actual Results: Battery monitoring gives an erroneous (0% charge) reading in KDE. Wireless does not function. It is not possible shutdown ultrabook without holding down power key for 1/2 dozen seconds or so. Even a 'shutdown -h now' results in PC hanging during shutdown. Expected Results: Both wireless and battery status/management should function correctly after resuming from suspend. It should be possible to shutdown the PC via openSUSE software. Additional information of the logs from this laptop can be provided per request. Note this is likely a Toshiba ACPICA issue addressed by an upstream kernel fix. It would be useful if this fix can be trialed in an openSUSE kernel update, as an interim until the upstream fix makes its way downstream. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
