Up until recently, this NIC was reported to work. I booted our 2.6.5-based SLES9 kernel on it. This is the kernel the machine has been running for a while with the NIC working, and when I booted it, I got the same DMA failure messages as with 2.6.16-rc4. I suspect that the hardware has just recently failed, and I figured it was a hardware problem when I saw the NMI/DMA messages, but since I don't have physical access to the hardware, immediate removal wasn't an option. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFD/JX2LPWxlyuTD7IRAiKOAKCmFcjKzmyJEVF63hsm5zxPFVwNBACdHTR7 CghdO/WCfh4mwCaH1uwh1fc= =Z5Ey -----END PGP SIGNATURE-----
