Hi,
recently I switched some components in my home-pc. 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
