I'd check PS voltages, reseat RAM, run memtest, etc.

It's failing in trying to copy a pixmap via EXA, that could be any number of hardware or software causes. Does it happen in pre-3.9 kernels?

You could try AccelMethod "glamor" as a workaround (but it might just make things worse).

older kernel fails. somehow I doubt that glamor will do the trick.

next order of business it hw checking.

didn't reseat ram as I've figured that if something is bad, memtest will pick it up but memtest run didn't found anything.

but on the other hand, I've took a look on the trace again, this time in developer mode and I've noticed that this might an issue of xf86-video-ati as I'm using the git version.

so I'll first try to downgrade it, if it works, I'll open a bug at freedesktop, if not, I'll fire up my multiseat config and see if it is a gpu issue.

ok, xf86-video-ati-7.0.0 seems to no crash, 7.1.0 crashes.

also I see frequent kernel panic, I got a huge one with radeon and one with reiserfs.

any hints what might be wrong?

Frequent kernel panic can be a sign of failing or overheating hardware. See what happens if you limit CPU frequency via /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq

You better sanitize the situation first, i'm not sure how is your configuration (using intel + radeon) ?
But your system is a little mess :
Code:
[  3040.296] (II) Loading /usr/lib64/xorg/modules/drivers/ati_drv.so
[  3040.296]    compiled for 1.14.1, module version = 7.1.99
[  3040.296] (II) Loading /usr/lib64/xorg/modules/drivers/radeon_drv.so
[  3040.297]    compiled for 1.14.1, module version = 7.1.99
[  3040.297] (II) Loading /usr/lib64/xorg/modules/drivers/intel_drv.so
[  3040.297]    compiled for 1.14.1, module version = 2.21.6
[  3040.297] (II) LoadModule: "vesa"
[  3040.297] (II) Loading /usr/lib64/xorg/modules/drivers/vesa_drv.so


4 drivers to handle 2 cards ?
I also find strange ati_drv and radeon_drv have the same version 7.1.99 (maybe cause i don't own an ATI).
vesa seems to unload itself later, intel is kept as working with the intel card, but i'm not sure of the ati_drv and radon_drv state, if both are loaded, i suppose they could mess trying to use the same card.
In log one is then RADEON(0) and other is RADEON(G0)
Funny to see name to help debug the thing in this case are not helping at all, as it get confusing of who is who, lol ok maybe not for the INTEL(G1) name.

Until someone confirm it's normal to have ati_drv and radeon_drv, i would consider that an error. And i would try kick radeon_drv first, as it is the one that crash in your log.

I would also look those ones
Code:
[  3040.936] (WW) RADEON(0): [DRI2] Direct rendering is not supported when VGA arb is necessary for the device
[  3040.936] (WW) RADEON(0): Direct rendering disabled

I have a coolermaster 212+ hsf, I doubt it is a heating issue but I'll check non the less.

I have 3 cards, radeon 5450HD, radeon 3650 and intel igp, I'm using a multiseat config in general, I didn't fired it up because the system isn't stable yet.
my current main card is the 5450HD. the vesa I load as failsafe, is it possible that this can be the issue?

/usr/lib64/xorg/modules/drivers/ati_drv.so = /usr/lib64/xorg/modules/drivers/radeon_drv.so , e.g. the same driver.

I've noticed it too but as I didn't stabled the system yet, I don't mark it as high priority.

just to sum it all up, I had a working system, scraped it when I've added an sata to esata converter for a new backup drive and because when tried to install grub in my drive's mbr (root is a raid1 on 4 drives) failed on sd[b-d] (worked on sda) with inconsistent filesystem (still happens after reinstall so I assume the tutorial is wrong).
during the reinstall I've started to see the problem, infact I've installed gentoo quite alot but I've never has such install that took so long to get it to work.

I'll open the case and see if there is an issue with the cables there. maybe the sata to esata's cable got into a bad place within the case.

case opened, reseated all pci cards and brackets, even did some cleanup, still fails, even with stable version.

next up, booting the multiseat setup and see if it reoccurs, if yes, on what cards, if all, I think it is a mb issue, if only one card, than a gpu issue.

any others ideas I should try?

Did you check PS voltages under full load with a real voltmeter?

nope, sorry, it was on my list when I decided to do one last try, I've decided to load the multiseat config (to see if it is the gpu or the driver), I've also went to the radeon wiki entry and made sure that all the config keys were ok including the fw files. on the way I've upgraded my kernel and after reboot, no more crash.

I've even updated the drive back to the 9999 version and no crash.

until now the system didn't crashed yet, I'll see in the next few days and if it doesn't reoccur, I'll mark this as solved, I think the issue was the fw files.

system seems to be stable, the issue was probably fw, marking as solved, thanks to anyone who helped.
