I had something similar: https://mail-index.netbsd.org/current-users/2026/07/22/msg047762.html it occured several times, but I was running a -11 kernel with a -10 userland. I'm quite confident that this was triggered by firefox. I never noticed this while I was running a -10 kernel; and I've not seen it since I updated userland to -11. My CPU and graphic card is cpu0: highest basic info 00000016 cpu0: highest extended info 80000008 cpu0: "Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz" cpu0: Intel 7th or 8th gen Core (Kaby Lake, Coffee Lake) or Xeon E (Coffee Lake) (686-class), 2808.00 MHz So looks similar to yours. Even after upgrading userland to -11 I have lots of crashes related to graphic activity (not always kernel crashes but X11 was going out of control). I added Option "AccelMethod" "UXA" # <str> in xorg.conf and now it's stable again (I have 34 days of uptime now).

Just now I have: Memory: 5413M Act, 2375M Inact, 66M Wired, 371M Exec, 1646M File, 1981M Free Swap: 15G Total, 10G Used, 5198M Free / Pools: 4983M Used / Network: 21K In, 8K with a X session running for 34 days. firefox is still crashing occasionally -- Manuel Bouyer <[email protected]> NetBSD: 26 ans d'experience feront toujours la difference --
