Description mailrupile 2010-10-28 15:52:54 UTC

My ethernet card (Attansic Technology Corp. Device 1063) freezes on high in\out net traffic. 

If net traffic doesn't high (jabber and web surfing only) all OK. But if I'll run something like rtorrent or just try to download\upload one big file on good speed (>100KB) it will freeze.

atl1c is maintained by Atheros directly.  Calling upon Jie Yang to
look at this bug.

I can add that on windows 7, which I was forced to install due above transcribed problems, everything is OK. With eth-card, at least.
Thus this IS a atl1c driver problem.

Comment 10 mailrupile 2010-11-14 00:08:16 UTC

Problem solved in kernel 2.6.36-gentoo-r1 by driver version upgrade:

kernel 2.6.35-gentoo-r12
ATL1C_DRV_VERSION "1.0.0.2-NAPI"

kernel 2.6.36-gentoo-r1
ATL1C_DRV_VERSION "1.0.1.0-NAPI"

[26782.502214] Hardware name: VPCS13V9E
04:00.0 Ethernet controller: Atheros Communications AR8131 Gigabit Ethernet (rev c0)

Same problem with 2.6.37-1-amd64 on Debian unstable.

The fix isn't applied upstream yet?
