Subject/proc/interrupts vs. /proc/stat (and reality)
Hi,

my /proc/interrupts doesn't show all the interrupts that have been used,
/proc/stat (and hence procinfo) does. All of the devices work without
problems.

% cat /proc/interrupts /proc/stat && procinfo

So IRQ 3 doesn't know it's getting serviced by the serial module, IRQ 4
and IRQ 6 don't show in /proc/interrupts (and I've used both serial
ports and the floppy before), only in /proc/stat.

This is an Athlon 700 on a Gigabyte 7IXE (Irongate/Viper), gcc-2.95.3
compiled 2.4.4-pre4. Some lines from .config:

CONFIG_MK7=y
CONFIG_X86_GOOD_APIC=y
CONFIG_X86_MSR=y
CONFIG_X86_CPUID=y
CONFIG_NOHIGHMEM=y
CONFIG_MTRR=y
# CONFIG_SMP is not set
CONFIG_X86_UP_IOAPIC=y
CONFIG_X86_IO_APIC=y
CONFIG_X86_LOCAL_APIC=y


Have I done something wrong? Should I send more info?

Regards...
Michael
