Help -System crashed

Post by Kiwi » Tue, 16 Jul 1996 04:00:00



I have had FreeBSD 2.1 installed for a couple of months now but
recently the system panicked and rebooted.  After that I got constant
UID:0 signal 11 errors when booting.
The filesystem got messed up and i decided to restore from my backup.

The system is a cyrix 5x86 with 16Mb RAM
AHA 1542 SCSI host adapter
1 Gig fujitsu HD
SCSI CD Rom
2 gig tanberg SCSI tape
Didi 8 port
NE2000 clone

I booted into single user, fscked thesystem, mounted the filesystems
and restored my backup.  The system still constantly came up with
uid:0's signal 11's when going multiuser.
So I tried to re-install the system.  Using the same drive parameters
and file system sized 9default0 the system would error when trying to
put down the /bin etc directories.  I would get a wrote -1 byte of
10240, and my f4 screen would show more uid:0 signal 11 errors and a
core dump from gzip and cpio.
I tried it without the Digi and NE2000 - same thing

So I reformatted the disk and tried again, same thing.
I changed motherboard and RAM and got the same thing.
I was able to install Linux OK and tried FreeBSD again.  It would
install only if I changed the file system sizes from the default.
Once installed I tried to relink the kernel to get my digi ports back
and got errors compiling the kernel.

I guess my next move is to replace the SCSI controller and/or disk???

Can anyone shed any light onto what the problem might be?
Also what do the UID:0 signal 11 errors mean?
I have done a search through the freebsd.org archives but not found
anything helpful.

Thanks

Steve

That's surprising, it has been beaten to death in Usenet and on the
mailing lists.

This is most likely an indication of either bad memory, bad cache, or
a broken chipset that doesn't invalidate the cache at busmaster DMA
transfers of a peripheral device.

Try turning cache from write-back to write-through, turning the cache
entirely off, or replacing memory (in this order).

Never trust an operating system you don't have sources for. ;-)

No, I'd replace the cache on the motherboard first as it sounds like one
of the chips may have gone bad on you.

Exactly right. The error messages you describe correspond exactly to mine
when cache is not working correctly. As a fast test, disable External
cache and try again.

1. Help:system crashes,cannot boot

Hi !
This happened to me for the second time.
I bought the InfoMagic's 6-CD Set: Linux developer's resouce (April
1996 edition). And installed the slackware's linux 3.0 on my machine.
Mine is a Pentiem 75 (Canon MT 7030, INNOVA MEDIA). With
        16 Meg of RAM.
        a Western Digital 850Meg hd (master)
        a seagate 1.2Gig hd (slave).
I partitioned the seagate 1.2Gid into three partitions. hdb1 (700Meg)
was partitioned for Windows95. hdb2 (500 Meg) was partitioned for linux root.
And hdb3 was for swap. Yes, my linux partition is outside of the first
1024 cylinders.
After I installed linux. Everything seemed working fine. But, after a week
or so, one day, I heard some grinding noise of the hard drive. Then I
tried to close the running processes, but cannot. The system hang.
The soft boot (Cnt+Alt+Del) did not work. So I had to press the Reset.
Then I got the following error message when it was rebooting:
_________________________________________________________________
.....
Partition check:
 hda: hda1
 hdb: hdb1 hdb2 hdb3
EXT2-fs error (device 3/66) ext2_check_descriptors: Block bitmap for
group 32 not in group (block0) !
EXT2-fs group descriptors corrupted !
[MS-DOS FS Rel. 12, FAT 0, check=n,conv=b,uid=0,gid=0,umask=022 bmap]
[me=0x0,cs=0,#f=0,fs=0,fl=0,de=0,data=0,se=0,ts=0,ls=0]
Transaction block size = 512
Kernel panic: VFS: Unable to mount fs on 03:42
_________________________________________________________________

I did reinstall the system and after I reconfigured the network, the
sound system, the X-window . It happended to me again. You understand
how frustrating it is.

So if you have any idea what it is, please help !!!
Thank you very much in advance.
