Fedora 7 installs but system halts after crc error.

Fedora 7 Live runs in ram without any problem. dmesg output includes a line near the beginning:

"ACPI Warning (tbfadt-0360): Ignoring BIOS FADT rl c-state control [200701]"

Also,

"BIOS BUG: multiple APIC/MADT found. using 0

The first comment "ACPI Warning..." suggests to me that the Live version is ignoring the crc-error instead of halting the system. If so, is there something that can be added to the boot command line to enable the installed Fedora 7 to also ignore the crc-error?

Measures I have taken to rule out sources of the crc-error are:

1) Removed memory modules, replacing them one at a time - trying each separately. System recognizes all memory.
2) Removed DVD RW to eliminate it as a source since I was getting SQUASHFS messages indicating errors.
3) Installed different flavors of Linux and checked integrity of install source. No matter. All create crc-errors and the system halts.
4) Have run disk checking software and both drives - also tried them seperately and both pass the "long" self check.
5) Cooling fans all function properly.
6) Even tried installing WindowsXP - but the installation program could not find a drive...
7) BIOS setup and Linux have no problem recognizing the drive(s).

Finally, dmesg also indicates:

"ATA:abnormal status 0x8 on port 0XF8A3431C"
"ata3 disabling port"

Does this simply indicate the second drive is not installed when in fact it is not?

Why, when the Linux kernel is so efficient at finding and identifying the guts of a computer - can't it report what the source of a crc error is instead of just halting the system?

It would be nice to have a functioning system that ignored a crc-error and thus provides a means for finding the source of the error.

Flummoxed!

Looks like you need to enter "linux noapic nolapic" at the boot: prompt. Maybe "noacpi" either. If you installed, but this happened on first boot, then you want to add these options to the kernel line in /boot/grub/grub.conf

But you should go carefully through your BIOS and turn off any special power management support above the minimum.

I resolved the tbfadt warning by enabling the built in card readers. But,...

Additional information:

The system was working fine before first crc-error. See my thread below for background info.

http://www.linuxquestions.org/questi...d.php?t=564008

All memory modules were removed, then tried alone, one by one. Still crc-errors.

I have come to the conclusion there is something amiss with the boot sector, preventing any and all flavors of linux from completing a fresh install. Install continues to 100% stage, then fails with;

<6> SELinux: initialized (dev hda, type iso9660), uses genfs_contexts
<5> SQUASHFS error: zlib_fs returned unexpected result 0xfffffffd, src length 65536
<5> SQUASHFS error: Unable to read page, block 1e0aa28, size 4f86"

My first thought was a problem with the DVD RW/CD drive. But I believe the SQUASHFS error is referring to the boot sector of the hdd.

Comments repeat several times and install stops without successfully installing the boot loader and grub.

I suspect a boot virus and my next step is to "dd if=/dev/zero of=/dev/sda bs=512 count=1" the boot sector (just in case dban didn't affect the boot sector). I have already used dban to zero the drive with one pass.

Additionally, when I tried to install FC6, the install quit with the following message:

"Traceback (most recent call last):

File "/usr/sbin/authconfig, line 26 in?
import authinfo, acutil
File "/usr/share/authconfig/authinfo. py", line 32 in?
import urllib2
File "/usr/lib/python2.4/urllib2.py", line 108, in?
import cookielib
<Space>,<+>,<-> selection /ValueError: bad marshal dataF12
>next screen"

Using TestDisk 6.6 Data Recovery Utility (02/07) Drive specifics are:

/dev/sda - 100GB/93GB - CHS Cylinders 12161, head 255, sectors/track 63, sector size 512.

Given that sector sizes can vary, which is best? 512, 1024, 2028, etc.?

Finally, the ranish partition manager reveals unused space before sda1 and at the end of the drive. This unused space is not displayed by Disk Druid, parted or fdisk.

Any ideas?
