Subject: Two suggestions (loop and owner's of linux tree)

Hello

I would like to suggest to change max_loop from 8 to 16 or more if it
possible.

-static int max_loop = 8;
+static int max_loop = 16;
static struct loop_device *loop_dev;
static int *loop_sizes;
static int *loop_blksizes;

My second suggestions is a request for change owner linux tree from 1046
uid and 101 gid to 0.0 for security reason.

max_loop=16 in your kernel command line if you use loop builtin or:
options loop max_loop=16 in /etc/modules.conf if you use it as an
module.

chmod -R root.root linux/
after you have unpacked the tarball.

I know about this option, but I think limit max=16 is much better.

Unnecessarily extra command :) Sometimes I can forget about this and then
user with uid 1046 can modify my kernel source.

Simply unpack and compile the kernel as a normal user, not as root.
Only install the new kernel as root. Get into the habit of logging
in as a normal user and doing root stuff with 'su' or 'sudo'

I disagree: presumably increasing the limit takes resources, in which case
a fairly low default is best.

errr. chown perhaps? :)

Just give UID 1046 to a new user, "linus" :)

Not mounted loop devices too?

You just bumped loop memory usage by 24000 bytes on my system with
something that can be handled with a boot parameter. I'd rather see a
max_loop = 4 or something patch instead...

Subject: Asus CUV-266-D vs Intel NIC

I have an Asus CUV266-d motherboard, and want to use my Intel NIC's..

2.4.10 & 2.4.12 hangs while "Setting up routing"
No error messages appear.

2.4.x(4 maybe?) has both officail Intel drivers and the tulip drivers.
When loading the tulip, it hangs just like with todays kernels.
When loading the Intel driver, everything works just fine for a short
while..
20-40seconds I guess.. Then the computer hangs.

When not loading any NIC drivers, everything works just fine.

The NIC's i've tried are named "Intel(R) PRO/100+ Dual Port Server Adapter"
Have also tried a "Intel(R) PRO/100+ Adapter"

Any ideas of what to test?
I have the latest bios and have tried just about all bios settings.
'noapic' doesn't help.

Tested now with another motherboard with the same results.

MSI 6321 Pro 1.0

Both these motherboards use VIA dual-cpu chipsets.

Same results with 2.4.13-Pre6 on both motherboards.
I'm running out of ideas now..

Ooopss...

I have to excuse my error.. I said I used the tulip driver, but I don't.

When I said 'tulip', i meant the 'eepro100' driver.
When I said 'intel', i meant the 'e100' driver

Sorry for any confusion..

Jeff: 'de4x5' didn't work. Not so strange I guess.. =/
