Summary: i386 SMP : IRQ routing problems Kernel Version: 2.5.68 Status: NEW Severity: blocking Owner: mbligh@aracnet.com Submitter: josh@stack.nl
Distribution: Mandrake 9.1 Hardware Environment: Dual PII 333 on Intel 440 LX SMP mainboard Software Environment: Bare shell after kernel boot Problem Description: CPU 1 stops accepting interrupts, APIC IRQ rerouting doesn't work. As a result, only CPU 0 receives timer interrupts (and thus I got practically an UP system), and my devices don't work when IRQ rerouting (MPS 1.4 in my BIOS) is enabled, for they claim the wrong (read: the one before rerouting) interrupt line.
NOTE: both bugs also occur in the 2.4.21 kernel that Mandrake 9.1 ships, but as this is a Mandrake-hack you might not really care. Other 2.4 kernels untested at this moment.
Steps to reproduce: Check /proc/interrupts after booting.
To check whether it is a Mandrake thing, I cleared the lilo append options, removed the Mandrake initrd, and performed a sulogin first thing after entering rc.sysinit. This didn't affect the problems.
On the URL : http://www.stack.nl/~josh/linux/ you should be able to find all files / output that might be useful in solving this.
