Subject:   Lock order reversal in ral driver
Message-ID:  <200803232052.07111.robertjenssen@ozemail.com.au>

next in thread | raw e-mail | index | archive | help
Hi,

Since upgrading to FreeBSD 7 I have been experiencing some frustrating 
problems with my RAL wifi card. In particular, it seems to me that dhclient 
fails when the ral device driver times out while scanning for my access 
point. At the same time my HP PDA with Spectec WiFi SDIO card has no problems 
finding my access point.

Today I made a kernel with the following options:

makeoptions     DEBUG=-g
options         INVARIANTS
options         INVARIANT_SUPPORT
options         WITNESS
options         DEBUG_LOCKS
options         DEBUG_VFS_LOCKS
options         DIAGNOSTIC
options         SOCKBUF_DEBUG
options         DDB
options         KDB

Upon rebooting the dmesg immediately showed a lock order reversal in the ral 
driver in ieee80211_scan.c and rt2560.c (see below). Does this correspond to 
my symptoms? Is there a wizard out there who understands what is happening?

Thanks in advance,

Rob
