[Bug 1249256] [NEW] hp-wmi calls WMI 0x05 instead of WMI 0x1b interfaces in new BIOS

 

Public bug reported:

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."

** Affects: linux (Ubuntu)
