I'm trying 2.6.18-rc1, on a Thinkpad T60 (dual-core, T2400) running Ubuntu 6.06. The kernel is SMP, PREEMPT, and has many of the lock validation options turned on. It has a SATA hard drive. During boot the lockdep checker reports good news: [ 20.936404] Good, all 218 testcases passed! | When I pressed Fn-F4 (for suspend-to-ram), it began to suspend, blanked the screen, and then came back right away to the X session. I don't think it ever made it into suspend mode. And this dmesg showed up: [ 459.756000] BUG: warning at kernel/lockdep.c:1799/trace_hardirqs_on() [ 459.756000] [<c0105aeb>] show_trace+0x1b/0x20 [ 459.756000] [<c0105b14>] dump_stack+0x24/0x30 [ 459.756000] [<c013c186>] trace_hardirqs_on+0x166/0x180 [ 459.756000] [<c010522d>] do_general_protection+0xcd/0x220 [ 459.756000] [<c0103e01>] error_code+0x39/0x40 With the Ubuntu kernel (2.6.15-25-386, which is UP and has many Ubuntu patches), S3 suspend/resume worked almost out of the box, amazingly. The only glitch was I had to tell it unload/load ipw3945 if I wanted the module to work correctly on resume. But suspend/resume worked fine at least 50 times, with only one failure that I couldn't reproduce. So I'm not sure what the vanilla 2.6.18-rc1 is missing. Here are its dmesgs after grepping for ACPI or lockdep: [ 0.000000] BIOS-e820: 000000005f6e0000 - 000000005f6f3000 (ACPI data) [ 0.000000] BIOS-e820: 000000005f6f3000 - 000000005f700000 (ACPI NVS) [ 0.000000] ACPI: RSDP (v002 LENOVO ) @ 0x000f68a0 [ 0.000000] ACPI: XSDT (v001 LENOVO TP-79 0x00001060 LTP 0x00000000) @ 0x5f6e6342 [ 0.000000] ACPI: FADT (v003 LENOVO TP-79 0x00001060 LNVO 0x00000001) @ 0x5f6e6400 [ 0.000000] ACPI: SSDT (v001 LENOVO TP-79 0x00001060 MSFT 0x0100000e) @ 0x5f6e65b4 [ 0.000000] ACPI: ECDT (v001 LENOVO TP-79 0x00001060 LNVO 0x00000001) @ 0x5f6f2d29 [ 0.000000] ACPI: TCPA (v002 LENOVO TP-79 0x00001060 LNVO 0x00000001) @ 0x5f6f2d7b [ 0.000000] ACPI: MADT (v001 LENOVO TP-79 0x00001060 LNVO 0x00000001) @ 0x5f6f2dad [ 0.000000] ACPI: MCFG (v001 LENOVO TP-79 0x00001060 LNVO 0x00000001) @ 0x5f6f2e15 [ 0.000000] ACPI: HPET (v001 LENOVO TP-79 0x00001060 LNVO 0x00000001) @ 0x5f6f2e53 [ 0.000000] ACPI: BOOT (v001 LENOVO TP-79 0x00001060 LTP 0x00000001) @ 0x5f6f2fd8 [ 0.000000] ACPI: SSDT (v001 LENOVO TP-79 0x00001060 INTL 0x20050513) @ 0x5f6e58fd [ 0.000000] ACPI: SSDT (v001 LENOVO TP-79 0x00001060 INTL 0x20050513) @ 0x5f6e5725 [ 0.000000] ACPI: DSDT (v001 LENOVO TP-79 0x00001060 MSFT 0x0100000e) @ 0x00000000 [ 0.000000] ACPI: PM-Timer IO Port: 0x1008 [ 0.000000] ACPI: Local APIC address 0xfee00000 [ 0.000000] ACPI: LAPIC (acpi_id[0x00] lapic_id[0x00] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x01] lapic_id[0x01] enabled) [ 0.000000] ACPI: LAPIC_NMI (acpi_id[0x00] high edge lint[0x1]) [ 0.000000] ACPI: LAPIC_NMI (acpi_id[0x01] high edge lint[0x1]) [ 0.000000] ACPI: IOAPIC (id[0x01] address[0xfec00000] gsi_base[0]) [ 0.000000] ACPI: INT_SRC_OVR (bus 0 bus_irq 0 global_irq 2 dfl dfl) [ 0.000000] ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 9 high level) [ 0.000000] ACPI: IRQ0 used by override.
