On the new Xperia Z almost all USB Sticks works (had a chance to test)...

Any other kernel supports all usb sticks????

Figured out the problem, my /system partition remaining was less than 7MB while the modules size is pretty darn big about 9MB
So i cleaned up my system a little bit, reflash modules, then voila the wifi works

I have a strange problem. I'm on ICS HD Supernova Build 7 and have an LT18i. So for some reason Vengeance Kernel doesn't work. It seems to be normal till I reboot. It stuck at Sony Logo. If I change Kernel this doesn't happen. I really like to use this Kernel. Is there anything I can do?

Thanks in advance

probably bad init.d scripts as vengeance does not run them on first boot...try deleting everything from /system/etc/init.d

That works. I deleted everything as you said and now Vengeance boots normally One question. Now as the whole init.d folder is deleted...does this effect performance negatively?

0+3 records in
0+3 records out
384 bytes (384B) copied, 0.000579 seconds, 647.7KB/s

[email protected]:/dev # dd if=random of=null bs=1M count=1
dd if=random of=null bs=1M count=1
0+1 records in
0+1 records out
128 bytes (128B) copied, 28.720093 seconds, 4B/s
as you can see random doesn't look so slow at first (648kB), but that is due SuperCharger tweak to keep entropy full 3MB...
....on second run when entropy is empy we see a real speed of random, 4B/s i.e SLOW

Test: /dev/urandom
Code:
[email protected]:/dev # dd if=urandom of=null bs=1M count=32
dd if=urandom of=null bs=1M count=32
32+0 records in
32+0 records out
33554432 bytes (32.0MB) copied, 27.944611 seconds, 1.1MB/s
Test: /dev/frandom
Code:
[email protected]:/dev # dd if=frandom of=null bs=1M count=128
dd if=frandom of=null bs=1M count=128
128+0 records in
128+0 records out
134217728 bytes (128.0MB) copied, 5.207428 seconds, 24.6MB/s
[email protected]:/dev # dd if=frandom of=null bs=1M count=512
dd if=frandom of=null bs=1M count=512
512+0 records in
512+0 records out
536870912 bytes (512.0MB) copied, 20.932007 seconds, 24.5MB/s
It is ultra fast and never empty....

What 20frandom script does is forcing android to use frandom instead random and urandom...

Test of random and urandom after running script (you don't need to run it manually it executes on boot if put in init.d):
Code:
[email protected]:/dev # /system/etc/init.d/20frandom
/system/etc/init.d/20frandom
[email protected]:/dev # dd if=random of=/dev/null bs=1M count=64
dd if=random of=/dev/null bs=1M count=64
64+0 records in
64+0 records out
67108864 bytes (64.0MB) copied, 2.818756 seconds, 22.7MB/s
[email protected]:/dev # dd if=urandom of=/dev/null bs=1M count=64
dd if=urandom of=/dev/null bs=1M count=64
64+0 records in
64+0 recordis out
67108864 bytes (64.0MB) copied, 2.673767 seconds, 23.9MB/s
From test we see android system uses frandom instead random and urandom....

Hi pro,
I'm not found random, frandom, urandom in /dev/ folder
