Comment 250 for bug 1239578

Ok, IRQ interrupts also happening on 3.11.10-301.fc20.x86_64 with new versions of driver downloaded from https://github.com/lwfinger/rtlwifi_new (master & troy, didnt try kernel version explycitly, but it should be probably at 3.18 kernel which also had the problem). Version downloaded (probably) from here http://netbook-remix.archive.canonical.com/updates/pool/public/o/oem-wireless-rtl-92ce-92se-92de-8723ae-88ee-8723be-92ee-dkms/ does not causes IRQ explosion, but wifi drops 80% and more packets, making it pretty unusable.
If you have any suggestions that I can try I will be happy to help. @Xprogrammer - if you can navigate me how to run virtualbox without VT-d (if it is possible) I will try it (i'm lets say little advanced beginer in linux...).
Also, I tried to limit only 1 cpu core to respond to IRQs sent by realtek driver by
echo 0 > /proc/irq/48/smp_affinity
didn't help, system also froze with more than 33000 IRQ interrupts per second.
If it is usefull, I can provide log from /var/log/messages but I couldn't find any info that seemed to be important...
this is really .... situation as probably every wifi card usable (whitelisted) in this laptop has some kind of problems...

also, in git versions of wifi.h should be changed line (~2455)
#if (LINUX_VERSION_CODE <= KERNEL_VERSION(3,11,0))
to maybe 3,12 (in 3.11.10-301.fc20.x86_64 aren't those variables defined, I had to change it to .12 to be able to compile drivers)
