Well, personally I wont' move any of our production machines or customer 
machines to 2.6 yet. It's still beta though it's "official stable" ;).

Personally I had a "small" ext3 corruption bug some days ago after I did:

echo 64 > /proc/sys/vm/nr_hugepages

(so bleh, I can't use Oracle. WTF :()

It gave me an oops, then almost no process worked anymore, calling new 
processes hung immediately, init 6 the same, so I did sysrq-b (like I always 
do when I reboot and never had a problem with 2.2 or 2.4: Even 2.2 ext3 0.07 
alpha code does no harm to my FS :P ... but after the reboot, my /lib 
and /usr/lib were almost completely fucked up. I had to reinstall tons of 
libraries (ELF header was fucked up). Well, but after that, 2.6 is up and 
running on one of my machines (desktop) w/o any problemas "yet" - We'll see.

Well, for my experience, 2.6-WOLK runs smoother as 2.4-WOLK, but that's 
generally a 2.6 "feature" and afaik only interesting for desktop usage.

I really miss grsecurity for 2.6. If Brad (grsec man) won't come up with a 2.6 
version soon I start looking at 2.4 current grsec code and try to port it, at 
least some of the important features.

2.6 does also miss some of the 2.4 security fixes, so I wouldn't put up a 2.6 
machine where remote users can do any harm or offer services to the internet 
with it. I'm gonna look into 2.4 security fixes soon and port them to 2.6 and 
forward them upstream.

Last but not bleh, if you have a big iron machine (say, 32 cpu's, 256gb ram, 
tons of $fucking_fast_whatever_SCSI_or_so) you'd like to choose 2.6-WOLK and 
no 2.4-WOLK ;)

ciao, Marc
