(The full bug report is logged at <https://bugs.debian.org/756947>.) This was reported against Linux 3.2, but I don't think there have been relevant fixes since then. Perhaps the hp-wmi driver should blacklist this model for wifi rfkill (while leaving all the others features enabled). Does that seem like a reasonable approach to fix this?

Assuming assertions about no more firmware becoming available and the latest firmware being run are accurate, blacklisting this model seems like a reasonable approach to restoring basic functionality.

Alan, can you provide the identifying information for this model: grep . /sys/class/dmi/id/{product,board}_{name,version} Ben. -- Ben Hutchings No political challenge can be met by shopping. - George Monbiot [-- Attachment #2: This is a digitally signed message part --] [-- Type: application/pgp-signature, Size: 811 bytes --] ^ permalink raw reply [flat|nested] 3+ messages in thread
