The situation is very serious that even ddb(4) could not be activated, hence I can not provide more useful information at present. Currently I am trying to figure out what caused the problem. The box runs 5-CURRENT built 20 days ago previously, it builds world and kernel periodically (twice a week or even more), it crashed today and therefore it is now running: FreeBSD beastie.frontfree.net 5.2-CURRENT FreeBSD 5.2-CURRENT #40: Tue Mar = 2 17:38:46 CST 2004 delphij@beastie.frontfree.net:/usr/obj/usr/src/sys= /BEASTIE i386 A friend of mine encountered similar problem on his Alpha box, as well as a VMWare contained FreeBSD/i386 guest. I'll post subsequent results here if I got some findings, and hopefully, a patch to solve this :-) Cheers, --=20 Xin LI http://www.delphij.net/ See complete headers for GPG key and other information. --huq684BweRXVnRxX Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFARKkmOfuToMruuMARAh0mAJ9nCcoZ9CprXsupc8oHJ6kHnchrZwCgh9eP rRImBLEqjfDLo1hryK2E9mc= =cM25 -----END PGP SIGNATURE----- --huq684BweRXVnRxX--
