Hi all, I often see freezes when I do much outgoing transfer. I have never seen this happening on incoming transfers. When this happens the system locks up hard, I don't see anything in the log. Since this is my laptop I have trouble debugging it: there is no serial console and debugging this via netconsole doesn't look like a good idea.
When I say "much outgoing transfer" this means "several megabytes". If I copy
out 30 MB I almost everytime get this. I usually copy that much only at home
when I feed my gentoo server. That host only has a 10 MBit connection.
Nevertheless I've also seen that on different hosts using different files on
different protocols (ftp, scp, smb).
This is the output of lspci for my NIC:

Hm, is there a reason why we don't use MSI here?
Ah, one thing is missing: I've not tested it with current kernel, latest I
tested was 2.6.21-rc7. But I've seen this on many previous version, although
I thought it became better some versions ago. I wont bet on it, it might just
have been luck.
