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.
debug.acpi.disabled="hpet timer"

Also, is it possible to see a picture/screenshot of the panic?

Best regards,

Hello,
I have attached a screenshot of the panic in the bug description.

Bests

Sorry, I overlooked the attachment.

I have some fixes for acpi_timer.c

Could I build you an ISO/IMG with them and you try booting with it?

Sascha

Hi,

can you rebuild the kernel (actually, just the acpi module should be enough) with this patch?

http://leaf.dragonflybsd.org/~swildner/0001-kernel-acpi-Convert-acpi_timer-to-using-ACPICA-funct.patch

Please test if this helps with the acpi_timer panic you were seeing. If it still panics, another screenshot would be nice.

Thanks,
Sascha

Also, could you tar the output of acpidump -b (it creates several .dat files) and attach it here?

Thanks,
Sascha

This patch:

http://leaf.dragonflybsd.org/~swildner/gobook_dsdt.diff

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.

Good luck,
Sascha

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)".

Regards

Thanks I'll try and let you know.

• 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.

Regards,
Sascha

Yes, I copied to that path and modified loader.conf to use that file.
Regarding timer if I boot without acpi the timer goes twice as fast. I have updated to master, I'll patch and recompile.

The kernel panic is produced when I remove the disable hpet timer line from loader.conf.

Can you give me 2 more things:

• Do "mptable -raw" (it will create /tmp/mptable)

• Do "mptable -verbose >/tmp/mptable.txt"

Please attach both /tmp/mptable and /tmp/mptable.txt to this issue.

Thanks,
Sascha

Hi, the only thing that is different from previous boot is that it freezes in this point acpi_ec0: <Embedded Controller: GPE 0x17> port 0x66,0x62 on acpi0
