Description of problem:
I hit <enter> at the boot: prompt after booting from the CD, and after the
installer finds my hardware, it shows a blue screen for a few seconds then
that goes away, and it says the installer exited abnormally with signal
7. I also tried lowres mode, but that gave the same result.
Steps to Reproduce:
1.Start install program in graphical mode
Actual Results: Installer exited and said I could now safely restart my
Expected Results: Installer should have asked desired boot mode (i.e. CD-
I'm running the following:
Abit KT7-RAID mobo (with Promise ATA-100 controller),
Creative 3D Blaster Annihilator 2 Ultra,
SB Live X-Gamer,
3Com 10/100 card,
HP CDWriter 9300,
ATAPI Zip drive
When the install crashes, can you press <Ctrl><Alt><F4> and see if there are any
error messages there?
The signal 7 has now changed to a signal 11. I checked where you said to look,
and the only thing that looked like an error was a line that read:
Unable to identify CD-ROM format
Also, there were some devices sharing IRQs, but that shouldn't be a problem,
Can you try booting with 'linux ide=nodma' and see if that helps?
I had already tried it, but I just got a different error at about the same
place. I'll try it again though and record the error.
I tried running linux ide=nodma, and again anaconda exited abnormally, but
without a Signal 11. Under <ctrl><alt>F4, nothing looked different than
before. Under <ctrl><alt>F3, the last line was "looking for USB mouse" but
that could be the same as before. Also, under F4, the last few lines were:
raid0 personality registered as nr2
raid1 personality registered as nr3
raid5: measuring checksumming speed
...(here it output some test results)
raid5:using function: p5_mmx (3284.800 MB/sec)
raid5 personality registered as nr4
I don't know if that last part means anything, but it was the last few lines
It's hard to say what the problem is. It's not getting far enough into the
installer for me to do any meaningful debugging. Can you look on VC1 and see if
you see a line that says "Running anaconda"? If you don't see that, then
anaconda hasn't even started, which means there either a kernel problem or
there's something wrong with the hardware.
It definitely did say "Starting anaconda"
Were there any more messages at all on <Alt+F1> ?
Actually, the error message changed again. The entire output after "running
anaconda" under <ctrl><alt><F1> is as follows.
Running anaconda -- please wait
exec: Exec format error
install exited abnormally
sending termination signals...done
sending kill signals...done
/mnt/source unmount failed ()
you may safely reboot your system
I see this same error on a dual-processor 1GHz Pentium III... Running on an
ABIT VP6, latest BIOS. It happens on both fail-safe and optimized settings.
I've tried everything I can think of to solve this, including disabling the USB
bus, turning off my Adaptec card, etc.
I see exactly the same errors as the previous reporting person.
I have an Adaptec SCSI controller with a single CD-RW attached. I can give
more thorough specs if you want.
try booting with "ide=nodma"
Just like before, that didn't work, but now I got a Signal 11 again. By the
way, I also tried Expert mode, and I got through a few screens, but anaconda
exited at the exact same point.
this is a data corruption error and will have to be handled kernel level.
So, what do I do about that?
This is almost certainly a hardware issue. I assume none of these systems
are overclocked ?
Nothing's overclocked at all. I've used the video card control panel to boost
the speed on that, but that should only affect the Windows driver, right?
Can you update me on this? It's been almost 2 months, and I recently tried it
again, getting the same errors. I'd like to know if there's been any
Somehow your cdrom drive has problems reading the cd. Would it be possible to
do either a network install or an install from harddisk (where you copy the cd's
(as iso files) to harddisk first) ?
