Hello,

I am having dual OS i.e. windows xp and RHEL 4. Both were running fine, but when i today wished to launch RHEL 4; i am getting

Unknown Interrupt or Fault at EIP 00010006 0000060 c06e97ec
Unknown Interrupt or Fault at EIP 00010006 0000060 c06e97ec
Unknown Interrupt or Fault at EIP 00010006 0000060 c06e97ec
Unknown Interrupt or Fault at EIP 00010006 0000060 c06e97ec

and cursor is blinking only.

I do'nt know what happened. Since i am newbie in linux, please tell me how to resolve the error. I have tried to reinstall grub; using linux rescue. Grub has been installed successfully, but error is still there.

After google or talk with others; i came to know that i have to acpi=off in grub.conf. So is it its solution? Will there any bad effect for acpi=off?

Thanks in advance.

See the related LQ thread What does acpi=off and nolapic means??

* FWIW: next time if you would actually use the term you're looking for information about in the subject line related theads will show up in the "Similar Threads" box at the bottom of this page.

Thanks for your reply and interest in the thread. I have tried with
"acpi=off" (with/without quotes) in grub.conf just before title Microsoft Windows XP line, but still i am not able to run RHEL 5 (sorry, earlier i posted RHEL 4).

Can you boot the RHEL installer CD in rescue mode? What last happened before you were no longer able to run RHEL?

Hye

does the problem occur after a complete poweroff? or after warm booting from windows into Linux?

Thanks once again for prompt reply.

Yes, i am able to boot with RHEL CD-1 after linux rescue... and chroot /mnt/sysimage. Here i added acpi=off/"acpi=off" in /boot/grub/grub.conf (as other google link suggested); but still i am getting the same error.

Actually, on that home pc my cousin was reading/testing some fdsik commands (as he said) and then he shutdown the machine without any issue; but today when i wished to run linux.. since then it is returning errors.

In that linux, i have installed oracle 11gR2, Netbeans, apatche etc. etc. softwares (all for reading purpose); so i do'nt want to reinstall all these things; if you please help me to avoid re-installation.

Please help me.

0) making backups would be a Good Thing, but I guess you realize that too by now, 1) if you boot the Live CD you can review the shell history of every user. While this won't leave traces for commands run from within fdisk you might get an idea what he has actually done. Especially if he had root account access. If he's done something bad just send him to the other side of town to buy some Durian ;-p One other command you might want to run from your rescue shell is 'rpm -Vva|grep -v '^\.\{8\}';' as it might show you any changed (configuration?) files.

I am really thankful to you for your support. Please check below where i am wrong :

sh-3.1# chroot /mnt/sysimage
sh-3.1# 'rpm -Vva|grep -v '^\.\{8\}';'
sh: rpm -Vva|grep -v ^.{8};: command not found

It returned command not found error. Please help me sir..!!

Try w/o outer quotes and with proper quoting: but a quick win would be to find user history files first ('find /root /home -maxdepth 2 -type f -iname .bash_history') and read those.

sh-3.1# rpm -Vva|grep -v '^\.\{8\}' > F1.txt
and F1.txt contains :
