The backtrace points to an incorrect call from RTMPFreeTxRxRingMemory()
into linux_pci_unmap_single(). This appears to have been fixed in Linux
2.6.33 by this change:
commit ca97b8388838ee9ea4b4bad04948f8f7f8a607a3
Author: Bartlomiej Zolnierkiewicz <bzoln...@gmail.com>
Date: Tue Sep 22 20:44:07 2009 +0200
Staging: rt28x0: updates from vendor's V2.1.0.0 drivers
For stable-2.6.32, just fix this one function call.
