Hello I am Ioannis Barkas.You can contact me at risc4all@yahoo.com. There is a typo error in the comments area of linux-2.6.12.5\arch\alpha\lib at the files checksum.c csum_partial_copy.c I found this bug after visiting http://www.knoppix.net/wiki/Bugs/3.9-2005-05-27.I had submitted bug # 24).Next day I visited it again for additional comments and someone else had reported bug # 25) about a suspicious typo error in the knoppix boot menu help.That time it was clear and obvious to me that the kernel would suffer from this error.Here I note that the unknown guy deserves some credits on this patch.DESPITE THAT,I HAD THE FINAL IDEA TO CHECK THE ERROR INSIDE THE WHOLE LINUX KERNEL.Luckily it affected only those two files. This error is repeated also in previous kernels such as the 2.6.9 .
