This is probably another bug because: 1. I built kernel with INVARIANTS as described in on "Debugging Deadlocks" page of FreeBSD Developers' Handbook and got no panic, but only deadlock; 2. I have no NTFS filesystem at all and just do a copy of file(s) from FTP to local UFS using mc. In this PR panic occured when NTFS mounted r/w (and NOT occured when the same NTFS mounted r/o). -- Oleg Derevenetz <[EMAIL PROTECTED]> OOD3-RIPE Phone: +7 4732 539880 Fax: +7 4732 531415 http://www.vsi.ru CenterTelecom Voronezh ISP http://isp.vsi.ru _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
