Title:
hp-wmi calls WMI 0x05 instead of WMI 0x1b interfaces in new BIOS
Status in HWE Next Project:
In Progress
Status in “linux” package in Ubuntu:
In Progress
Bug description:
Some hp systems have faulty wmi 0x05 interfaces
(HPWMI_WIRELESS_QUERY); however, BIOS still reports 0x05 is supported
and it will be used in hp-wmi instead of wmi 0x1b
(HPWMI_WIRELESS2_QUERY). This causes "rkfill block" and "rfkill
unblock" fail to change the state of wireless devices in these
particular systems.
HP defines wmi 0x05 as "This command is deprecated starting with
Bios09 platforms and is replaced by Command Type 1Bh. Check Features
Reporting (Command Type 0Dh, Bit 3) for new command support."
