Won't boot from boot disk - "crc error"

Won't boot from boot disk - "crc error"

Post by Scott MacFarla » Tue, 27 Feb 1996 04:00:00

After botching a kernel upgrade, I tried to make a new boot disk
so I could get back into my system and reconfigure. I
keep getting this error: "crc error" just after it starts
expanding linux from the boot disk.

I have tried multiple diskettes thinking I had
a bad diskette, but this doesn't help.

I am running an PCI/IDE 486/66. Linux was
running great before this on this system.

Any help would be greatly appreciated.

Please respond to this newsgroup as
my email is history as well. :^(

Hi Scott.  I had the exact same problem as you.  Mine was caused by a
bad hard disk.  Probably munged it due to "botched" kernel upgrade or
something.  It eventually did not even work with DOS.  Note that the
CRC error is very confusing and appears misplaced.  It occurs when
booting off floppy, but it has nothing to do with the floppy.  I
sniffed around for hours with a hair dryer (trying to get the floppy
or the controller to fail), and even ended up replacing the floppy
drive.  That did not help.  A loud screech and bang from the hard
drive necessitated its replacement and solved the problem.  Note that
the strings command executed on the kernel image will find this
annoying message, so in principle, at least, you can hunt it down in
the kernel source and force a more informative error message to be



1. "syslogd: unknown priority "24" " error - won't boot!

I have upgraded from 1.2.13  to 2.0 & was in the process of upgrading the
associated files.  Last nite I upgraded to util-linux-2.5.tar.gz, & when I
rebooted I got a "syslogd:  unknown priority "24"" error and my system hung.
to yes, my intent was to next update these using sysvinit-2.6.2.tar.gz.
The compilation of util-linux-2.5 went OK unitl an error on cal.c for not
having /usr/include/localeinfo.h.  I looked at the Makefile for the section
with cal.c & saw that cal was the only thing which complained about this so I
removed cal from the Makefile in the misc-utils directory.  The make then
worked fine (just using "make").  I then did "make install" & rebooted & got

        Starting daemons: cron lpd
        fcntl_setlk() called by process41(cron) with broken flock() emulation
        /bin/hostname Permission denied
        syslogd:  unknown priority "24" " error

Now the system will not boot!

Is there something obvious that I did wrong?  My (uneducated) guess is that
should have updated the sysvinit-2.6.2 stuff BEFORE rebooting. I had  
previously never upgraded either the linux-utils or the sysvinit stuff
since I did my initial install from the Yggdrasil Fall 94 distr.

The obvious question now is how do I fix this?

How I got there:

http://www.signet.com.sg/~sunsurf & installed the following packages in this
order (I already had gcc 2.7.2):

2.0 kernel compilation

I rebooted & everything worked fine.  I then began updating the other
suggested packages:

procinfo-? (oops, don't remember this vesion)

I rebooted & this is where the show-stopping syslogd error occurred.

Any suggestions are much appreciated!
