chromium causing PC to crash? (maybe)


i been using chromium for a good long while and it always seems fast and stable, but the last few months my PC would either lock up hard and require a reset with the power button, i look in /var/log/messages and syslog and i see a lot of malformed packets and invalid packet, so today i removed chromium and cleared the log files and switched to firefox and so far i am not seeing any malformed and invalid packet messages in the logfiles, i will run firefox for a few days at all the various websites i visit to see what changes i get

so i am asking has anyone else noticed anything like this while using chromium?, can malformed and invalid packets cause a PC to crash?

okay, i checked just now as i am typing this new thread, i see a couple of invalid packets listed in syslog, but so far no malformed packets, but there are less of them, chromium would give a lot of those malformed and invalid packet lines, are these serious or trivial?

Which version of Chromium? Did you compile from source, or do you use AlienBob's package? The latter works fine for me, no odd entries in syslog or messages.

alienbob's build found at slackware http://www.slackware.com/~alien/slac...pkg64/current/

running it on Slackware64 current on a Dell Inspiron that has a Ryzen7 and an AMD Radeon, the only suspect hardware i might consider is that AMD Radeon and i already have a GeForce to replace it with coming in the mail (i never liked ATI video cards)

it has been an hour and half since i switched browsers from chromium to firefox and the malformed and invalid packets messages have dryed up, i am not blaming alienbob, i would say it is the chromium developers if it is indeed chromium, because alienbob just builds a slackware package from chromium's source code

it seems i eliminated chromium as a suspected cause of my pc occasionally locking up, now i suspect it is my video card, but it still dont answer why i get lots of malformed and invalid packets while using chromium, but not firefox, i wonder if chromium is trying to call home to the google developers that build chromium to give them browser info

maybe the sync feature? i forgot about that, if i could rebuild chromium without that part even being in the final product it would be fine with me,

I guess you know by now that Ryzen needs the latest BIOS update, and set the BIOS option "Power Supply Idle Control" to "Typical Current Idle", to not lock up every now and then. Or maybe a kernel option rcu-nocbs=0-(numberOfCores - 1).

checked the kernel .config and that CONFIG_RCU_NOCB_CPU is already set to y

i been in the BIOS many times in the past and it is updated to the newest one Dell has for it, i will look again as soon as i reboot for the "Power Supply Idle Control" to "Typical Current Idle" but i dont think i ever seen anything like that feature concerning the power supply but i will look again to make sure of it,

nothing in the BIOS with any powersupply options and settings, none whatsoever, i will wait until i switch out the video card and see what comes of that, i had a PC with an ATI card before (before AMD bought them) and did not like that video card, and i dont think AMD improved them much, their website dont offer driver packages except for ubuntu and fedora, where Nvidia has a driver package that is distro agnostic that will work on anything as long as the kernel source is in place, but first i will get the FOSS Nouveau driver a chance and it works good i will stick with that

That rcu_nocbs is a kernel boot parameter. Like append="rcu_nocbs=0-15" in /etc/lilo.conf and then run lilo if you have 16 cores.

how would i add that parameter to grub?
Code:
append="rcu_nocbs=0-15"
i never manually edit /boot/grub/grub.cfg and use grub-mkconfig -o /boot/grub/grub.cfg

Curious ... I've always used 127.0.0.1 for nasty adware sites.

What is the advantage of entering 0.0.0.0 ( the default route ) and 127.0.0.1 ( localhost.localdomain ) ?

Thanks for any insight.

not sure of any advantage but it seems to work, i use it for adware-malware and some social media sites that i dont trust (facebook)

this is where i get it, i merge two files, the adware-malware and social media hosts file, plus i get rid of blank lines and comments to make the file a little smaller

scroll down about half way down where the hosts files are located
