Problem with USB1.1 Host cores with the mb tree for bcm43xx_mac80211

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
