I haven't tried the fix on Debian/2.6.18 yet but expect that it will work there too. Side note: 2.6.20 wasn't happy with the networks (I gave up waiting in the end) but it was reporting lots of unaligned accesses. I haven't took a look to identify the offending bits of code/structures but following are typical console messages. Kernel unaligned access at TPC[51cf0c] Kernel unaligned access at TPC[51cf0c] ip_fast_csum+0x14/0x80 ip_fast_csum+0x14/0x80 Kernel unaligned access at TPC[51cf14] Kernel unaligned access at TPC[51cf14] ip_fast_csum+0x1c/0x80 ip_fast_csum+0x1c/0x80 Kernel unaligned access at TPC[5f1534] Kernel unaligned access at TPC[5f1534] ip_rcv+0xd0/0x588 ip_rcv+0xd0/0x588 Kernel unaligned access at TPC[51cf04] Kernel unaligned access at TPC[51cf04] ip_fast_csum+0xc/0x80 ip_fast_csum+0xc/0x80 Kernel unaligned access at TPC[51cf08] Kernel unaligned access at TPC[51cf08] ip_fast_csum+0x10/0x80 ip_fast_csum+0x10/0x80 Regards Richard - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
