This machine isn't under load but runs rsync every 5 minutes. amr0@pci3:1:0: class=0x010400 card=0x05181028 chip=0x19601000 rev=0x01 hdr=0x00 vendor = 'LSI Logic (Was: Symbios Logic, NCR)' device = 'MegaRAID' class = mass storage subclass = RAID # uname -srm FreeBSD 6.1-RELEASE-p3 i386 ... with just this KERNCONF: include GENERIC ident PE6650 options SMP options COMPAT_FREEBSD4 options COMPAT_FREEBSD5 The amr seems more stable since "Scott's Mega Update" (see: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/amr/amr_cam.c?rev=1.15.2.1&content-type=text/x-cvsweb-markup&only_with_tag=RELENG_6_1_BP ) but probably under high load or after a while it still fails (no disk access possible, no messages). Has anyone else running a Dell PE6650 with this LSI RAID? Anyone else got this errors? Regards Raphael Becker On Thu, Jun 22, 2006 at 12:17:12PM -0300, Marc G.
