Now I am getting trouble when trying to do a "make world". (btw. I am using FreeBSD-current usually less than a couple of days old) This one worked like a champ.: Old System: i486DX/100, 32MB, Ati-Mach32 EISA, SIS-EISA-MB, Adaptec 1742A, Quantum PD1800S, Seagate ST3283-SCSI, SCSI-I CD-ROM, HP 35450A-DAT, wd8013-Clone here comes the trouble-maker: New System: El-Cheapo 486-PCI-MB /w. 256KB-Cache and UMC-Chipset (something like 8881 and 8886, IDE-Crap disabled) Miro-SV40 (S3-968,4MB), NCR 53c810-SCSI rest is the same (Memory, CPU, Disks ...) Problem: make world fails after some time with misterious sig11 or sig10. (takes usually up to 2hrs. to reproduce) or System hangs. So far checked: switched memory-timing to slowest possible (Wait-States, refresh) switched second-level-cache to "write-trough" switched second-level-cache off switched PCI-Bursts off PCI-Cards in different slots Old VGA instead of PCI-S3-Card used only 16MB-Memory Are there any Ideas of what I could check? Has anyone some further knowledge about the UMC-PCI-Chipset? Are there possibly some Problems? Any help appreciated Micha ------------------------------------------------------------------------- michael class michael.class@zdv.uni-tuebingen.de ZDV Uni-Tuebingen, Morgenstelle C2-P28, Tel. +49 7071 29-7539 PGP-Public-Key: finger Michael.Class@x500.uni-tuebingen.de -------------------------------------------------------------------------
