Hi, Lately this machine is freezing while using random graphical applications, the other day happend while doing some scrolling with firefox, today while selecting some tag in a dialog in gbdfed (a little gtk2 application to edit fonts.)
I got only this one line message: panic: kernel diagnostic assertion "flags & (M_NOWAIT)" failed: file "/usr/src/sys/kern/kern_malloc.c", line 176 dmesg: OpenBSD 7.2-current (GENERIC.MP) #1075: Fri Feb 24 10:09:47 MST 2023 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 4135260160 (3943MB) avail mem = 3990528000 (3805MB) random: good seed from bootblocks mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.4 @ 0xeb920 (70 entries) bios0: vendor Hewlett-Packard version "786E1 v01.16" date 08/17/2011 bios0: Hewlett-Packard HP Compaq dc7700 Convertible Minitower acpi0 at bios0: ACPI 1.0 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP APIC ASF!
