Hi! I ran into an problem while setting up linux on a laptop (HP dv6155eu; amd64 cpu). I'm posting here because I found some pointers to ACPI and DSDT problems when I searched for this. When I (or the init scripts) access the hwclock the system often - not always - freezes. It never worked for more than 5 times in a row. This are the commands that I used to test it: hwclock --show and hwclock --directisa --show I did test this with various kernel versions and different distributions (grml amd64+i386, kubuntu 7.04 i386, gentoo amd64). It seems that everything works well on i386 systems, while on all amd64 systems it freezes. It also seems to work on grml amd64 when I pass acpi=off as kernel-option and loaded the rtc kernel module afterwards. I was unable to test it with kubuntu 7.10 amd64/i386 because both versions froze at boot time, with a blank screen, which may or may not be connected with this problem. Windows XP seems to work fine on this laptop. If this is not the right place to request help with this problem, please tell me where it would be better suited. Please tell me what information you'd need to help me. greetings Roman - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
