Slackware 12.2 on HP 6910p halts but does not reboot

Hi there,

lots of smart folks here, so perhaps you can help. My HP 6910p halts and shuts off just fine under Slackware 12.2, but does not reboot properly. On reboot, it gets all the way to the BIOS (where you normally could hit F10 to enter BIOS setup) but then it hangs (and F10 actually does nothing). At that point, I have to hit the power button and do a cold restart.

This was the case with the stock 2.6.27.7-huge-smp kernel, and is the case with my custom 2.6.27.9 kernel. I have tried all kinds of "append=" options in lilo.conf, such as "reboot=...", "acpi_os_name='Microsoft Windows NT', "acpi=force", and some others (I lost track), but nothing helps, the system always hangs on reboot.

I have a ATI X2300 graphics card and an Intel HDA sound card with Conexant Winmodem, all of which are recognized properly, of course.

I have also configured SLUB in my custom kernel, rather than SLAB. Could that be a problem? And I have full ACPI support configured as well, but no APM. Any help would be much appreciated.

Regards and Thanks,

Matt Koch

Welcome to LQ.

I don't think SLUB or SLAB have anything to do with this. But, I do think you should try using APM instead of ACPI, that might help. So maybe pass 'acpi=off', but make sure you have the apm module available.

Hi there,

and thanks for the quick answer. I don't mean to question your wisdom, but when recompiling the kernel, APM is listed as deprecated or some such, and ACPI is listed as the preferred power management. Are you thinking my BIOS is so old that it would only work with APM? I bought my HP-6910p laptop in August of 2007, and it had just come out then. When did ACPI supersede APM? Also, I had tried "acpi=off" as one of the first attempts, and that did not make a difference, though I do not have APM installed at all.

Thanks,

Well, so far I'm thinking it could be one of two things:

1) Issue with power management, ACPI and APM, switching from one that does not work to one that works may solve the problem.
2) Misconfiguration of BIOS. I hear newer laptos have a "quickboot" option, and a "full boot" option, it should be on "full boot".
