spent some days to get 2.6 running in a mpc860 based board. while 2.4 runs fine, I couldn't manage to make it work until today. with help of some fine people in #mklinux we figured the problem: this board has registers mapped in physical address 0xFF000000. to make use of them, the 8xx port maps it to the same virtual address, i.e. 0xFF000000 virtual. this is not a problem in 2.4 but in 2.6 it is because kernel by default reserves an area beginning in 0xFF100000 for allocating consistent DMA areas. guess what: I hit in a WARN_ON() on dma_alloc_init() and interrupts just don't work (hangs trying to register inet socket types as it depends on rcu, which works using tasklets). easy, wasn't it? :)
I just finished to take a look in my uncle's computer. amazing, he got a computer about two weeks ago and it was full of trojans and all sorts of crap. and he's using firefox, firebird and AVG anti virus. seems another don't-open-strange-attachments problem.
I still don't understand what those flight companies do in web based sales. If I check for a flight to/from Toronto I got prices like US$2000,00 and up. Now, ask one of those travel agencies. US$1000,00. well, anyway seems I'm really going to OLS this year, despite all cabal and stuff.
