Bug #387

bge driver not SMP-safe in DEVELOPMENT?
Added by schlesinger about 18 years ago.
Updated about 18 years ago.
Description
If I use a SMP-kernel (with options "SMP" and "APIC_IO" enabled on a Lenovo
Thinkpad R60 (bge0 is identified as "Broadcom BCM5751M Gigabit Ethernet, ASIC
rev. 0x4201"), I get repeated the error message "bge0: watchdog timeout --
resetting".
When I build the same kernel as UP (with options "SMP" and "APIC_IO" disabled),
the bge0 interface works without problems.
I've used the 1.7.0-DEVELOPMENT sourcecode from Nov, 21.

I've forgotten to mention this: I get a reply, when I ping on the bge0's IP
address, but not on any other (valid) adress.
I don't think it is a problem in bge(4)
Can you post the vmstat -i of your UP kernel,
and vmstat -i of you SMP+APIC kernel before and after watchdog timeout.
BTW, please try turning off ACPI.
Best Regards,
sephe
vmstat -i with MP kernel after loading bge module, but before bge0 watchdog
timeout
vmstat -i with MP kernel after bge0 watchdog timeout
It doesn't make a difference, if I boot with or without ACPI on a MP kernel,
the problem appears in both cases.

See if MP works with the PIC. Try compiling a SMP kernel without
APIC_IO.

Compiling the kernel with SMP, but without APIC_IO did the trick.
Thanks!

Ok. This is not what we want to have to do, but I guess it seems to
work as a temporary bandaid.

seems it is not related to bge, but to interrupt routing
