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.
Hint: boot with "elevator=cfq" for desktop :)

Also some other users on #kernelnewbies and such channels on IRC use 2.6 for a
long time w/o any problems.

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.

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
