#12197: xo-4 page faults on boot. mwifiex?
----------------------+-----------------------------------------------------
Reporter: pgf | Owner: dsaxena
Type: defect | Status: new
Priority: normal | Milestone: 13.1.0
Component: wireless | Version: Development build as of this date
Keywords: | Next_action: reproduce
Verified: 0 | Deployment_affected:
Blockedby: | Blocking:
----------------------+-----------------------------------------------------
i've seen this failure multiple times, using os6. still trying to
reliably reproduce. it always occurs just after mwifiex has initialized.
for that reason, and because no one with an 8686 card has seen this, i'm
assigning the ticket to 'wireless'.
the next lines in a normal boot are:
{{{
