THC problem

GRUB_CMDLINE_LINUX_DEFAULT="quiet isolcpus=1 acpi_irq_nobalance idle=poll"
 

Ok after I make the change to the grub as above I then use crontab to create an operation to run the pinirq script a boot time. With a ctrl x to write it.
@reboot chmod +x pinirq,txt
sudo ./pinirq.txt eth0    should there be a @ at the beginning of this line too???

the script is already on the hard drive from the last time I used it

You don't need to chmod +x more than once so
chmod +x pinirq,txt in unnecessary (and will fail
because crontab has no idea where pinirq.txt is located)

Not sure about crontab and sudo
(will it ask you for a password during startup?)
So the systemd method of launching scripts at startup
may be better

Note that sudo ./pinirq.txt eth0 will fail because again crontab
does not know where pinirq.txt is located (you need a full path
or copy pinirq.txt to a standard executable directory like /user/bin/
Also pinirq.txt should probably be renamed just pinirq or pinirq.sh
(it only has the .txt suffix because that's required to be able to post it to the forum)

@reboot is what tells crontab to do the operation only at boot time

How about @reboot (full path location) pinirq (renamed just ) pinirq
next line ./pinirq eth0

@reboot  sudo pinirq eth0 

assuming pinirq is in /usr/bin/

done deal I can move it and remove the .txt from it
Thanks

wow, thank you
