Hi !
I run FreeBSD ( 2.2 BETA and 2.2R) on the one computer about
4 months and never seen any system crashes, except the msdosfs bugs,
system console locks if I try to mount bad msdos media ( diskette/hdd) .
Few days ago I try to move filesystems code from kernel to LKMs-
such as NFS, CD9660, MSDOSFS. It works good, but I for first time in my
expirience with FreeBSD on this machine see actually seriuos system crash:
Fatal trap 12: page fault while in kernel mode, supervisor read,
page not present
Fault virtual address = 0xuglyc0de
Kernel dumped at swap device 1 .
I see thats when I try to mount not very good WORM-CD ( recorded 680MB,
can see only about of 400MB).
I see crashes of FreeBSD only on broken motherboards. We had
5x86 motherboard with broken RAM subsystem. Kernel regularly paniced with
message " Double Fault ".
Any suggestions ?
Thanks , Vasily .
