If i use this NIC to download a big file ~60MB, the file get corrupted. I can get an ip address using dhcp and normal internet browsing is working. I can log on an ftp server and browse for files. This a 2 port NIC, i experience the same problem on both ports. Also, we have 2 of those cards and both doesn't work properly. We also have the same problem with knoppix 3.7 (kernel 2.6.9) and an old redhat distribution using the 2.4 kernel. If we use any other NIC on the same system, everything work as expected. Finally, our Intel 82546EB cards works perfectly on OpenBSD. Reproducible: Always Steps to Reproduce: 1. Get a Intel 82546EB Gigabit NIC 2. Configure the card, dhcp work fine for me 3. Download any big file, i downloaded install-x86-minimal-2005.0.iso from gentoo.risq.qc.ca 4. Run sha1sum on the file you just downloaded, this is what i got the first time: 87c0cf79d39a911490945072f7c11bf8c6e0927d install-x86-minimal-2005.0.iso 5. Remove the file and download it again. 6. Run sha1sum, the second time i got these results: e888f435fe6e0373a5af8bd7c4b12cf7eabc720e install-x86-minimal-2005.0.iso 7. Repeat, the sha1 hash will be different every time. Of course, the file is useless. Actual Results: Any big file get corrupted if i use a Intel 82546EB NIC on linux 2.4 or 2.6 (gentoo, knoppix 3.7, redhat). No corruption occurs if i use another NIC. Expected Results: My data should not be corrupted even if i use a Intel 82546EB NIC.

Please try and reproduce on the latest development kernel (currently vanilla-sources-2.6.12_rc6)
I was able to reproduce this bug with the latest and greatest development kernel (vanilla-sources-2.6.12_rc6) I did exactly the same test, i downloaded install-x86-minimal-2005.0.iso several times and the checksum was different every time.
Good news, i dowloaded the new driver from Intel, (e1000 version 6.0.60-NAPI), compiled it as a module and my card now work properly. You can download it from here: http://downloadfinder.intel.com/scripts-df-external/confirm.aspx?ftpDown=ftp://aiedownload.intel.com/df-support/2897/eng/e1000-6.0.60.tar.gz&agr=N&ProductID=983&DwnldId=2897&strOSs=All&OSFullName=All%20Operating%20Systems&lang=eng
The in-kernel driver should be fixed. Please report this bug to http://bugzilla.kernel.org with the same info (config, lspci -vv, dmesg) and post the new bug URL here.

If you have time, please test with 2.6.13_rc6 (soon to be released) and update the usptream bug as appropriate. If it is still an issue I will attempt to get the bug listed on Andrew Morton's to-be-fixed list :)
Should be fixed in recent kernels according to the maintainer
