I guess I would try tcpdump next. >> atapci0: using PIO transfers above 137GB as workaround for >> 48bit DMA access bug expect reduced performance this is a hardware bug on the Ultra 5/10 that's CMD/Silicon Image's fault. Sun never added a workaround to their driver---they just refuse to ship the machines with >80GB. I didn't know the SunBlade 100 had the bug, too. In theory, it means exactly what it says. In practice, I've found IDE on Ultra 5/10 is so crappy and such a time-sink that I avoid it like the plague. On FreeBSD/NetBSD I use SCSI or netbooting, and on Solaris I use SCSI, FireWire with Oxford 911 firewire cases only, and the iSCSI initiator to IDE targets in i386 boxes. Each of those has its own problems. (respectively: expense, expense and smartctl doesn't work, and kernel panics when you unplug the network cable.) In general I've had so many small problems with IDE on not-i386: I have some PCI card that will work at Ultra100 speed in NetBSD/i386, but in NetBSD/macppc it only works at Ultra33. Some cards don't work right unless the chip is initialized by their secret proprietary PeeCee BIOS. The problems never get fixed or explained. I don't know if there is something about the chips that assumes i386 or what. Reliable storage on noti386 has been a major frustration for me, so I guess you'll have to try it and see. good luck. :/ --pgp-sign-Multipart_Sat_Apr_28_11:32:33_2007-1 Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (NetBSD) iQCVAwUARjNpO4nCBbTaW/4dAQLgkwP/SxgbKYIIPiUoAaMQzBqKuuJ4hhCdUY7e 1L8JqLZ9gq5sDUCRyGRUOreLOSefH8wO8eygJcH7jvDuOhySWBXJYzgrhpocBMAP B2jHT/pOE77VlVy5BbJDrCjIekYuFp5qYpY6ogP8b8sFZ00hHo19/Eo5pgsL9NTp S8PaUhttYZk= =MrCK -----END PGP SIGNATURE----- --pgp-sign-Multipart_Sat_Apr_28_11:32:33_2007-1--
