I upgraded to the i386 version of 6.8-Release on three different Thinkpads R40E. On all of them, chromium fails to start, saying "Unable to allocate memory".
I suppose these are so ancient that it's hardly surprising (can't be mamy still around), but I thought I'd report it anyway. Here is the dmesg: OpenBSD 6.8 (GENERIC.MP) #440: Sun Oct 4 18:33:20 MDT 2020 dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC.MP real mem = 2137407488 (2038MB) avail mem = 2082074624 (1985MB) random: good seed from bootblocks mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: date 08/29/06, BIOS32 rev. 0 @ 0xfd6b0, SMBIOS rev. 2.4 @ 0xe0010 (68 entries) bios0: vendor LENOVO version "79ET67WW (1.11 )" date 08/29/2006 bios0: LENOVO 1951WAZ acpi0 at bios0: ACPI 3.0 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SSDT ECDT TCPA APIC MCFG HPET BOOT SSDT SSDT SSDT acpi0: wakeup devices LID_(S3) SLPB(S3) EXP0(S4) EXP1(S4) EXP2(S4) EXP3(S4) PCI1(S4) USB0(S3) USB1(S3) USB2(S3) USB7(S3) HDEF(S4) acpitimer0 at acpi0: 3579545 Hz, 24 bits acpiec0 at acpi0 acpimadt0 at acpi0 addr 0xfee00000: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: Genuine Intel(R) CPU T2400 @ 1.83GHz ("GenuineIntel" 686-class) 1.83 GHz, 06-0e-08 cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE,SSE3,MWAIT,VMX,EST,TM2,xTPR,PDCM,NXE,PERF,SENSOR,MELTDOWN mtrr: Pentium Pro MTRR support, 8 var ranges, 88 fixed ranges cpu0: apic clock running at 166MHz cpu0: mwait min=64, max=64, C-substates=0.2.2.2.2, IBE cpu1 at mainbus0: apid 1 (application processor) cpu1: Genuine Intel(R) CPU T2400 @ 1.83GHz ("GenuineIntel" 686-class) 1.83 GHz, 06-0e-08 cpu1: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE,SSE3,MWAIT,VMX,EST,TM2,xTPR,PDCM,NXE,PERF,SENSOR,MELTDOWN ioapic0 at mainbus0: apid 1 pa 0xfec00000, version 20, 24 pins, remapped acpimcfg0 at acpi0 acpimcfg0: addr 0xf0000000, bus 0-63 acpihpet0 at acpi0: 14318179 Hz acpiprt0 at acpi0: bus 0 (PCI0) acpiprt1 at acpi0: bus -1 (AGP_) acpiprt2 at acpi0: bus 2 (EXP0) acpiprt3 at acpi0: bus 3 (EXP1) acpiprt4 at acpi0: bus 4 (EXP2) acpiprt5 at acpi0: bus 12 (EXP3) acpiprt6 at acpi0: bus 21 (PCI1) acpibtn0 at acpi0: LID_ acpibtn1 at acpi0: SLPB "PNP0A08" at acpi0 not configured acpicmos0 at acpi0 "IBM0071" at acpi0 not configured "ATM1200" at acpi0 not configured acpibat0 at acpi0: BAT0 model "COMPATIBLE" serial 1242 type LION oem "SANYO" acpiac0 at acpi0: AC unit online acpithinkpad0 at acpi0: version 1.0 acpicpu0 at acpi0: !C3(100@17 io@0x1015), !C2(500@1 io@0x1014), C1(1000@1 halt), PSS acpicpu1 at acpi0: !C3(100@17 io@0x1015), !C2(500@1 io@0x1014), C1(1000@1 halt), PSS acpipwrres0 at acpi0: PUBS, resource for USB0, USB2, USB7 acpitz0 at acpi0: critical temperature is 127 degC acpitz1 at acpi0: critical temperature is 99 degC acpidock0 at acpi0: GDCK not docked (0) acpivideo0 at acpi0: VID_ acpivideo1 at acpi0: VID_ bios0: ROM list: 0xc0000/0xe400!
