Good try (new bios) but didn't help, after N+1 fsck's on a 1tb raid, I
decided to downgrade.... (sigh) but now I have an empty playbox which still crashes!!!! I am able to isolate the problem only non-raw accesses of >1m blocksize causes the system to crash: dd if=/dev/wd0d of=/dev/null bs=1040k count=100 --- DOES NOT CORE dd if=/dev/wd0d of=/dev/null bs=1200k count=100 --- DOES CORE !!!! dd if=/dev/rwd0d of=/dev/null bs=1200k count=100 --- is fine too. ( Raw device ) dd if=/dev/wd1d of=/dev/null bs=2000k count=100 --- is fine ( P-ATA drive ) wd0 is a 1tb sata drive (ffs - no raid) Any expert got any ideas? (I used the 5_0 iso from ftp.netbsd) I have a core dump of the crashed system (ask and I put it somewhere) - below is a dmesg before the crash. it very reliable produces "ohci4: 8 scheduling overruns" messages before crashing. So I disagree with the flaky memory timing hypothesis and I think it is a bug in the SATA/kernel area . (If someone wants access I can open an ssh port to the box and I can install a serial port redirector to the console plus a CVS checkout ) thanks for any help. thilo Copyright (c) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008 The NetBSD Foundation, Inc.
