Summary: Hang on boot when USB-stick attached
Product: ACPI
Version: 2.5
KernelVersion: 2.6.25-rc8
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Distribution: Ubuntu 7.10
Hardware Environment:
ASUS P4C800 Motherboard, P4 2.8 GHz, 2x 512 mb Corsair memory
Seagate ST3120023AS harddisk, SATA 120gb
Nvidia GeForce 4Mx graphics card
ps2 mouse and keyboard
Plextor cd-writer
samsung dvd-reader
Problem Description:
My computer hangs on boot if I have certain usb sticks attached to it while
booting. With a Sandisk Cruzer Micro 512 mb the bug happens, with a 1gb
Kingston it doesn't.
The initial initializing of the kernel seems to go fine, but it seems likes it
hangs when it comes to the ACPI part.
On the mainline 2.6.25-rc8 kernel, the last message it outputs is just:
ACPI: Core revision 20070126
On the Ubuntu 2.6.24-12 kernel, it also outputs
ACPI: Looking for DSDT in initramfs... error, file /DSDT.aml not found
The cursor still blinks, indicating the system is not completely locked up, but
ctrl-alt-del does not work, I have to make a hard reset via the computers reset
button.
I'm guessing that this problem should be filed under ACPI rather than somewhere
under USB, but please tell me if I should do otherwise.
During boot, the BIOS detects and initializes the usb-stick as a mass storage
device, maybe this has something do with the problem. I've not been able to
turn this behavior off from the BIOS.
Steps to reproduce:
Put in the Sandisk Cruzer Micro 512mb usb stick into the usb port.
Boot into linux
It hangs
