--- Comment #45 from Lv Zheng <zeta...@gmail.com> 2012-06-28 13:11:37 --- Sorry for my written English. You can just do a simple test by feeding "noapic" to your kernel instead of "acpi=off". If this can work, your platform should be one of those evils. According to Len Brown's documentation, when acpi is off, IO-APIC could act as a conventional 8259 PIC. Linux would always use 8254 PIT as its source of jiffies, this IRQ would be routed to IRQ0, pin 0 or 2, while Windows would use RTC from IRQ8. Some vendors will create such illness platforms that can pass windows tests while it's not suitable for linux as they haven't noticed the difference on PIT between ACPI on and ACPI off. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
