Hello! Myself, and many others (according to google search results on this laptop model), have troubles with ACPI and the HP laptop series tx1000. (My exact model number is tx1250eo). I am running Arch Linux with "uname -a" output: Linux DreadX 2.6.22-ARCH #1 SMP PREEMPT Wed Sep 26 20:57:40 CEST 2007 i686 AMD Turion(tm) 64 X2 Mobile Technology TL-56 AuthenticAMD GNU/Linux When just booting without any special kernel options it complains about apic. When passing the noapic option to the kernel at boot it does boot - but just to complain about ACPI a moment later. What happens is that it outputs something like this: "...output... ACPI: bus type pci registered PCI: Using MMCONFIG PCI: No mmconfig possible on device 00:18 Setting up standard PCI resources ACPI: System BIOS is requesting _OSI(Linux) ACPI: Please test with "acpi_osi=!Linux" Please send dmidecode to linux-acpi@xxxxxxxxxxxxxxx ACPI: Interpreter enabled ACPI: (supports S0 S3 S4 S5) ACPI: Using PIC for interrupt routing" ...and the "pausing" the booting process! But when I just hit my power switch on the laptop - it resumes the boot process! (And ACPI seems to be working fine after this - the system starts as it should). A strange thing is that the above only happens when booting with the power cable plugged in. When trying to boot without the power cable (running on battery power) it "pauses" the booting process several times at different occasions after hitting the power switch...almost for every new line that appears on screen...not just one time... Very strange indeed... Well, the message said to email the output from dmidecode to this email address, so that's what I'm doing below. Please let me know if you are going to do something about this problem. Best regards Simon Lundmark The remaining text in this email is the output from "dmidecode": # dmidecode 2.9 SMBIOS 2.4 present. 20 structures occupying 827 bytes. Table at 0x000F0BD0.
