speed improvement with kernel 4.2.5 / 4.3.3 / 4.6.6

[andjohn]

Thanks!

a new kernel, this one is the latest stable release of the linux kernel, 4.3.3
Behavior seems the same as 4.2.5 regarding up and download speed compared with 3.14.2
So no improvement in write but significant improvement in read.
The seg fault with the find command caused by /proc/usbconf is solved in this kernel

please test, remember this is beta testing so there is some risk.
Installation same procedure as for 4.2.5

--edit there is a new kernel with a patch for bug in mv643xx driver

Done so far.

The speeds are even slightly higher than in 4.2.5.

New kernel 4.3.3 installed without problems, I'll test it tonight and post an update.

A USB stick plugged in at front connector is recognized.

Q: what file systems are supported here ?

[fvdw]

Ext2, ext3,ext4,xfs,reiser, fat32,ntfs(slow writing!).
If you want this stick also in a windows pc and file size limit of 4GB is no problem then fat32 is a good choice for an usb stick.
Also use md-dos partition table. (No real need for gpt as size will be lower then 2TB.) gpt is not supported by several devices, forcexample my car media system doesn't recognize usb sticks with gpt partition table

New kernel is working great! No errors in dmesg or anything.

[wd9895]

Same here.

So it seems 4.3.3 elimnated the bugs we saw in 4.2.5 :punk

Version 4.3.3 looks much better:

Rsync restore backup ran without problems:

sent 341773 bytes received 47410529925 bytes 12332129.46 bytes/sec
total size is 47403553464 speedup is 1.00

I mentioned a difference to kernel version 3.14.2 concerning the fan control (2big2):
With kernel version 4.3.3 the fan runs always at full speed, with kernel version 3.14.2 the fan speed was only as high as necessary.
