           Version: 2.5
    Kernel Version: 2.6.38
          Platform: All

              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Network

        Regression: No


I have the SIS191 gigabit ethernet card on HP EX470. Had the MTU bug and
changed it from 1500 to 1024. All seems to work fine until I started transfer
large files. At some random point, sometimes after transferring a few hundred
MB, sometimes even a few GB of data ca be transferred, the driver will stop
working. Both TX and RX large files will fail.

Logging in at the console, the interface is still up according to ifconfig. But
no traffic can go out. Bringing the interface down and restarting it brings
everything back to normal. Nothing special on dmesg when the interface goes
down. Kernel doesn't hang or panic.

Tried Ubuntu and Gentoo, many different versions of the kernel. All failed the
same way. Currently running 2.6.38.

This output of lspci:

I heard that 32 bit kernel doesn't have any problem but haven't tried it. I'd
like to fix this issue myself if someone can point me to the right direction.

Let me if any more info is needed. Thanks!
