Subject: Problem with USB1.1 Host cores with the mb tree for bcm43xx_mac80211
Date: Wed, 07 Mar 2007 14:27:01 -0600 [thread overview]
Message-ID: <45EF2015.8000802@lwfinger.net> (raw)
If you have a BCM4311 and are seeing an oops that looks like this when loading bcm43xx_mac80211:
ssb: Switching to ChipCommon core, index 0
ssb: Switching to PCI-E core, index 3
ssb: Switching to USB 1.1 Host core, index 2
Unable to handle kernel NULL pointer dereference at 00000000000002d0 RIP:
[<ffffffff8812fcfd>] :usbcore:usb_create_hcd+0x3b/0xe8
PGD 3e792067 PUD 3ed66067 PMD 0
Oops: 0002 [1] SMP
...
there is a temporary, unofficial patch at
ftp://lwfinger.dynalias.org/patches/mac80211_usb_problem.patch. Although it works, it attacks the
symptom, not the cause, and will never be adopted into the code. Once a proper fix is applied, it
will no longer be needed.
