SubjectInvalid operand messages in 2.4.5-ac24
From
Date
Hello,

yesterday I compiled and booted 2.4.5-ac24 and got several 'invalid
operand' messages in the syslog. I have attached two, decoded with
klogd.

I have only seen these with -ac24, -ac22 was fine (skipped ac23), and I
have yet to see them with 2.4.6-ac1.

I am not sure what would cause these errors, but I do know they appear
in -ac24 only, relatively quickly.

Hope this helps,
kind regards,

Roel Teuwen
