Summary: ACPI bug reported, and system frozen if an USB is
connected to the USB 3.0 connector
Product: ACPI
Version: 2.5
Kernel Version: 3.2.9
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: BIOS
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No
I've experienced strange problems with my Dell Vostro 3750 machine.
If I boot it with an USB device connected to one of USB 3.0 enabled ports, the
machine freezes during the boot, and the last message displayed is:
[Firmware Bug]: ACPI(PEGP) defines _DOD but not _DOS
(That's why I fill this bug report against the ACPI subsystem)
However during successful boots this message is also displayed.
I attach four logs obtained in different configurations:
test7_ftdi.log - FTDI converter connected to the USB 3.0 jack - system frozen
test7_ftdi_nonxhci.log - FTDI converter connected to the USB 2.0 jack - system
booted, and rebooted normally
test8_disk.log - USB flash disk connected to the USB 3.0 jack - system frozen
test8_disk_nonxhci.log - USB flash disk connected to the USB 2.0 jack - system
booted and rebooted normally
(all files are zipped into logs.zip archive, to save space)
