Has anyone applied the patch to the tg3 driver that was shared in comment# 13? That one solved the issue for me. If that was the real fix, I'd like to inform the tg3 maintainers about it so that we can have it patched in the mainline. thanks. tp -- You received this bug notification because

Thank you for your valuable finding. I'll test your suggestion in the next few days to confirm that it works. I've also reported the work-around to Broadcom dev team and suggested a patch to the tg3 driver to disable highdma. I'll keep you updated on the issue... thank you once again. -- Yo

Lauri, Can you let me know if you've tested the work-around solution on a 64bit or 32bit OS? AFAK, HIGHMEM option only allows dma support on 64bit system (>4GB), so I dont think it would make a difference if the native OS is 32bit. The reason I am asking because I've tested the bug on both

Lauri, I've pumped over 1.5TB of data and have never seen the hic-up yet. I think we've found the smoking gun. Below is a simple patch to the tigon device driver if you prefer not to use the udev rule solution. I believe the root cause is that the tigon net driver uses virtual memory for DMA tr

It is confirmed, disabling HIGHDMA fixed the NIC problem. This was tested by putting a system under load for 120+ hours, and simulated over 12TB of data through the tg3 NIC. Great find Lauri, and thank you again! -- You received this bug notification because you are a member of Kernel Packages,
