I am having a problem with the tg3 driver locking up dual-xeon machines
when put under heavy load if and only if I am running an SMP kernel.
No problems with tg3+UP or bcm5700+SMP or with the a SysKonnect
card under load with either UP or SMP kernel.
The machines are:
dual 2.2GHz P4 Xeon/2GB RAM/Super Micro P4DL6 MOBO running
RedHat7.3 plus whatever kernel is needed. Besides the on-board
Broadcom BCM5701 10/100/1000 copper GigE there is one SysKonnect9843
fiber GigE PCI card and 2 3Ware IDE-RAID cards per machine.
I first ran into this with RH2.4.18, and reproduced the problem with
vanilla 2.4.20 and 2.4.20 plus tg3 1.4c patch at that time. It is now
a more important issue and I am seeing it with RH smp-2.4.20-13.7 but
not the uni-processor 2.4.20-13.7--both of which use the tg3 1.5 driver.
Any suggestions on how to get tg3 running stably under SMP
kernel on a BCM5701 interface would be greatly appreciated.
Here is the output of lspci -v.
