If your HME's PHY is DP83840 there are known issues on link neogotiation. AFAIK the issue has nothing to do with panic as I always see that on my Ultra2 which has DP83840 PHY too. I wonder how you can use NFS reliably on sparc64. Due to failure of alignment(both server and client) it's really easy to get panic on sparc64. > I tried to comment out the HME_WHINE line of hme_read() in if_hme.c, > and it seems to make the box work fine so far. HME_WHINE() just prints a message. I can't think removing the function can cure your problem. > Kris, could you try again?
