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\drivers\block at the file acsi.c There are two typo errors in linux-2.6.12.5\sound\usb\usx2y at the file usbusx2yaudio.c There is a typo error in linux-2.6.12.5\sound\usb\usx2y at the file usx2yhwdeppcm.c I found this bug after I had it repeated in some files on my HDD...That time it was clear and obvious to me that the kernel would suffer from this error..Luckily it affected only those three files.
