Hi folks,

does anybody have problem with 2.6.31-1-686 and eth0 (Broadcom
Corporation NetLink BCM5906M)?

I have up to date Sid on Lenovo ideapad S10e and approximately every 20
min. eth0 break's and little Tux from kerneloops.org notice me that he
will sent message about kernel problem.
WiFi works without any problem.

Goran Dobosevic

I had this problem in KVM virtual machines whose host has interfaces
NetXtreme II BCM5708 Gigabit Ethernet (rev 12). I obtained alternatings
timeouts:

Jun 25 19:07:18 ganimedes kernel: [5592587.125911] eth0: Transmit timeout, status 0c 0005 c07f media d0.

Jun 25 19:07:30 ganimedes kernel: [5592599.569338] eth0: link up, 100Mbps, full-duplex, lpa 0x05E1

With 'pci=noacpi' this problem was solved.

I hope this helps you.

Regards,
Daniel

Making a search on Internet, the first reference is bug #527209 in Red
Hat bugzilla. I recommend to you that you read the complete report.
They mention the following workaround:

# ethtool -K eth0 sg off

Also they give a patch to correct the problem. If it is a kernel
compiled with the source of kernel.org, it is necessary to see if there
is a patch or a new version of the kernel that solves this problem.

I hope this helps you.

Regards,
Daniel

Still the same. I think that I will wait for Debian patch.
Thank you for your help, I'm really thankful.
