Hmm, maybe ath5k is culprit. Could you apply the attached patch and use the kernel till the problem appears again? -- Make sure we print out a warning when the index is out of bounds, i.e. even on hw_rix == AR5K_MAX_RATES. Also change to WARN and print text with the reported hw_rix. Signed-off-by: Jiri Slaby <[email protected]> Cc: Nick Kossifidis <[email protected]> Cc: Luis R.
