Summary: PCI devices not working with ACPI enabled
Kernel Version: 2.6.16-rc4
Status: NEW
Severity: high
Owner: [EMAIL PROTECTED]
Submitter: [EMAIL PROTECTED]
Hardware Environment: AMD 64, ATI Xpress 200 chipset (MB MS-482M4)
Software Environment: Linux 2.6.16-rc4 32 bit
Problem Description:
If after bootup NIC (eth0, eth1) are assigned to IRQ5 by ACPI, then they are not
working. No interrupts from them recieved by kernel.
But if other device on IRQ5 (soundcard, for example) generates interrupts,
interrupts from NIC are passed and packets from network recieved.
If eth0 and eth1 are assigned to IRQ15 by ACPI, all works well. (it can be if
Linux boots after MS-Windows, and PC was not powered off between bootups of this
two OSes)
If kernel boots with "noapic nolapic acpi=off" all works well, inspite of eth0
and eth1 assigned to IRQ5.
My kernel config, and dmesg are in attachments.
With ACPI is on and this /proc/interrupts NICs are not working correctly:
CPU0

1: 693 XT-PIC i8042
2: 0 XT-PIC cascade

5: 298 XT-PIC HDA Intel, eth1, eth0
