Thank you. | | I'm afraid not all the chunks were merged since I cannot run on 6.x | with my BCM5709. | | FreeBSD 7.2 - works | FreeBSD 6.4-stable - does not | | It locks up somewhere in the late stage of multiuser (usually in a | random step of rc.d) and getty cannot take the control. | Here it still pings via network, I can achieve ssh stage where ssh | warns me "The authenticity of host '$HOST' can't be established." | If I type "yes", then it stops here and no go. After return from ddb | it stops even ping until next reboot. | | I use boot via NFS/PXE, so it may interfere there, since rc.d usually | write something to disk, which is NFS-mounted here. | So it probably could run fine if booting from a local disk (I can't | test this setup). You might try to instrument the rc stuff even though you mention it appears random. Might try to make sure that it isn't re-initializing the network or something like that. I tried with a fresh checkout of 6-stable and I PXE booted it fine. A side note is that Dell's have a bug with their uarts starting with the 2950 rev 2 in which the TX does work with the speed that we do the reset. RX works fine so you can recover it with a {Ctrl}d since it doesn't always fail. | I've attached dmesg (doesn't differs much from 7.2) and some ddb output below. | Looking in alltrace I see no obvious lockups, no nfs stuck. But | sometimes sh stucks somewhere in nfsreq. | | The same box boots fine via NFS on different NFS setup with 7.2, | a different (in h/w) box boots fine on these NFS setup and NFS root, | so no mistakes in setup part. | | I remember that back to August I tried to boot 6.4 with what is in bce | of RELENG_7 on this box and it booted fine and I xmitted some traffic | with it. | So I guess the problem is in NFS-boot. | | I'll try to find ways to boot the system locally and report back.. I didn't see anything in the logs. Doug A.
