Kernel page faults installing 2.1.6

Kernel page faults installing 2.1.6

Post by L. Scott Emmon » Thu, 23 Jan 1997 04:00:00



Anyone else getting kernel page faults while attempting to install
FreeBSD 2.1.6 (Walnut Creek CDROM dist)?

===
Fatal trap 12: Page fault while in kernel mode

virtual address  = 0x3200000
code             = Supervisor read, page not present
instruct ptr     = 0x8:0xf01a3f68
code segment     = base 0x0, limit 0xfffff, type 0x1b
                   DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL=0
current process  = 50 (cpio)
interrupt mask   = net tty bio
===

This has occured in the middle of the 'newfs' commands, or right
after when starting to extract te 'bin' distribution (which the above
info is from).

Have installed 2.0.5, 2.1.0, and 2.1.5 successfully on this machine in
the past...

My first install was almost succesful, however I discovered that I
couldn't create more than 6 filesystems + 1 paging (I guess an 8 slice
limit ('a'-'h')? Though I'm not sure why 6+1=8). Install turned the
last slice into "/dev/X", which was cute, but hardly helpful. So, to
take the easy way out I just decided to reinstall and collapse 3 of
the filesystems into a >1G /home. *SHRUG*. Shouldn't be a problem
since the max filesystem size is large, If I recall...

Anyone have any ideas?
-Scott

Kernel page faults installing 2.1.6

Not 2.1.6, but 2.2-BETA.  I have a P5/PCI machine that has a Vertos 4X
CDROM drive installed as a master device on the second IDE port.
Intermittently, boot-up will complain about "atapi, unknow phase", and
shortly thereafter produce a similar page fault.  Can't say as it's
exactly the same, because I finally took the drive out and moved it to
WinNT rather than fool with it.

1. Getting the fault adress in page faults.

Hi,

 I just wanted to ask, if there is a way in linux to get
the offending adress in a SIGSEGV-handler?
(Need that for a port. At least SunOS, OSF/1 and Ultrix support that feature.)

thx in advance,

Andreas Kostyrka
