Hey all, i was looking at smaller ones that were dupes of this, just found this.
It seems to be upstream, since I've had issues in other distros also. Here's what I have tried: Copied the debug instructions from wiki, added own comments: (it's all fairly clear) Try booting with the "acpi=off" kernel parameter This will disable ACPI support. If the error is the same with acpi enabled and disabled, this may not be an ACPI issue. If "acpi=off" allows the system to boot, try to isolate the ACPI issue with the following boot parameters Did that, boots fine then Try booting with "acpi=ht" This disables all of ACPI except just enough to enable Hyper Threading. If acpi=off works and acpi=ht fails, then the issue is in the ACPI table parsing code itself, or perhaps the SMP code. Try booting with "pci=noacpi" This disables ACPI for IRQ routing and PCI scanning. Try booting with "acpi=noirq" This disables ACPI for IRQ routing. All the above make it boot fine. Try booting with "pnpacpi=off" This disables the ACPI component of the Linux Plug and Play code. Try booting with "noapic" Disables the IO-APIC for IRQ routing or PCI scanning. Those two options make it boot, but same as original bug, need to press keys to force it to boot. Try booting with "nolapic" Disables the local APIC Boot fails at: "ata3: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata3.00:qc timeout (cmd 0xec) ata3.00: failed to IDENTIFY (I/O erroor, err_mask=0x4)" that's the main thing, then it says "Gave up waiting for root device" and then lists common issues, etc. Drops to Busybox. hardware: HP G6062ea, Atheros Wifi, nVidia 7000m nForce 610m, AMD Athlon X2 64 TK-57 1.9GHz Didn't happen in older kernels, not tried Jaunty yet. ** Description changed: Once the Ubuntu splash screen loads with the progress bar that moves back and forth, it freezes. Holding down any key unfreezes the system, and it continues loading normally, until I release the key, at which point it freezes again. Holding a key down again unfreezes the system again. Pressing Alt+F1 to show the output also freezes, so I know it isn't just the splash screen freezing, but the entire system. Once X loads, it works perfectly fine though, and I don't have to keep holding a key down. Update : This bug happens with 2.6.26 and 2.6.27 kernels with a computer that has Nvidia MCP67 motherboard. A known workaround that sometimes works is to add nolapic to GRUB boot kernel options. acpi=noirq is also known to work.
