kernel panics on acpi_timer_probe function
Booting with acpi module enable and hpet disabled in loader.conf results in a kernel panic, I'm unable to type anything in ddb as the the system is frozen
The hardware is a gobook vr-2 general dynamics itronix IX605 bios version 124. I'll update to bios version 125 and update the ticket if needed.

Have you tried disabling acpi_timer too like proposed on the IRC channel?
Please try with 'timer' added to debug.acpi.disabled, e.g.

can you rebuild the kernel (actually, just the acpi module should be enough) with this patch?
Please test if this helps with the acpi_timer panic you were seeing. If it still panics, another screenshot would be nice.

Thanks Sacha, I'll try the patch and let you know.
I have attached the acpidump -b contents, I'm trying to recompile dsdt.dsl using asl but there are several errors.
I was replacing things like CMSI = Arg0 to Store(Arg0,CMSI) maybe I'm mistaken to fix the errors.

should make the DSDT compile. Beware, while i'm pretty confident about the CAPB change, the Range Minimum/Length one is nothing more than an educated guess.

Also, beware that the patch is against a dsdt.dsl which was disassembled using master's iasl(8) program which recently introduced C-style syntax for operators. If yours is disassembled using an older iasl, that CAPB change should probably be "And (CAPB, 0xFFFFFFFC, CAPB)".

trying to use the fixed dsdt.aml failed with the message cannot load /boot/kernel/acpi_dsdt.aml.
I have applied your patch and commented the disable hpet timer, but it still panics I have attached a screenshot of this new kernel panic.

* Have you copied to dsdt.aml to /boot/kernel/acpi_dsdt.aml? (Note: different source and target names)
* Regarding the panic: Could you try with my patch and with _only_ hpet disabled? It was meant to fix the acpi_timer issue for which you previously had to also add "timer" to the disabled ACPI parts.
