 Description :
 
 I use the r8169 driver from the kernel-source-2.6.18 package on a Sun 
 Entreprise 450 (sparc64-smp) and got a bunch of aligned accesses on ip_rcv 
 followed by 4 unaligned access on ip_fast_csum, like that :
 
 Kernel unaligned access at TPC[5fd878] ip_rcv+0xf0/0x608
 Kernel unaligned access at TPC[52cac4] ip_fast_csum+0xc/0x80
 Kernel unaligned access at TPC[52cac8] ip_fast_csum+0x10/0x80
 Kernel unaligned access at TPC[52cacc] ip_fast_csum+0x14/0x80
 Kernel unaligned access at TPC[52cad4] ip_fast_csum+0x1c/0x80
 
 I tried a similar fix as the one suggested in bug #409313, which points to 
 this patch : http://article.gmane.org/gmane.linux.ports.sparc/7178
 
 Unfortunately, increasing the rx_copybreak for sparc does not help.
 
 If you need further informations, please let me know. I know the driver is 
 not 
 included by default in the linux-image-2.6-sparc64-smp package, and as soon 
 as this driver gets fixed, I could open a request for it to be included.
 
 Distribution is Debian etch freshly installed from yesterday.

Please note that this bug has been fixed upstream in 2.6.23-rc. Tested
successfully on an Ultrasparc 10.
