I see. E4500 has a DP83840 PHY, too. yo> I wonder how you can use NFS reliably on sparc64. Due to failure of yo> alignment(both server and client) it's really easy to get panic on sparc64. IIRC there are few NFS-related panics. I did not try heavy load, but massive read-only access to /home/ncvs works fine at least. yo> > I tried to comment out the HME_WHINE line of hme_read() in if_hme.c, yo> > and it seems to make the box work fine so far. yo> yo> HME_WHINE() just prints a message. I can't think removing the function yo> can cure your problem. I also think so, but the freeze surely happens at that moment. Very strange... Since doing "vmstat 1" on console when the message is displayed prevents the freeze, there may be a kind of timing-dependent problem. -- | Hiroki SATO ----Security_Multipart(Sat_Jun_11_16_49_48_2005_045)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQBCqpeeTyzT2CeTzy0RArQDAJ9ER/i2IZqnHR9LPehIEY3ahIXezQCfQ+P7 u31tCtSy1JxESrMt2ZKektg= =3OeU -----END PGP SIGNATURE----- ----Security_Multipart(Sat_Jun_11_16_49_48_2005_045)----
