Kernel sometimes takes four or five resets to boot successfully

Hello,

Running CRUX dual-booted with Windows 7 on two machines. On one
everything is fine. On the other, when I turn the machine on for the
first time in a day OR when I’ve just been in Windows and am switching
back OR a few other random times, it takes me four or five pushes of the
reset button to get it to boot.

I get part of the startup output and then just after the lines:
umount: /sys: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
mount: sysfs already mounted or /sys busy


I've been getting this message for quite a long time (don't remember
since which kernel vesion), but all my Crux systems boot and run
perfectly, so that's most probably not the reason for the kernel panic.


Anyway, I just looked into /etc/rc again, and got the impression that
the eroor is caused by the fact that /sys is already mounted when
/etc/rc starts. So I made the following changes in /etc/rc:


Comment out this line (ca. 13):
/bin/mount -n -t sysfs none /sys
and replace this (ca. 55):
/bin/umount /sys /proc
by
/bin/umount /proc

And indeed, the error message disappears, while /sys is still correctly
mounted. Give it a try, but keep in mind that I'm not a kernel
specialist! No guarantee!


As to the real boot problem: Could it be a problem with your harddisk?
Does the system boot reliably from CD-ROM?

Yes, it’s a bug in the /etc/rc script, and it’s never stopped my boot
before—I was just writing it in my message to indicate what stage the
script it at before the boot problem hits—thanks for providing a
solution to something I’ve been meaning to fix for ages though!

I’ve never seen the problem booting from a CD nor booting to Windows, so
I don’t think it’s a HDD problem.

Thanks for your reply.

Had the kernel panic too when configuring my kernel.
For me it was that the driver for my SATA-controller in "Device Drivers->Serial ATA and Parallel ATA drivers" didn't work correctly (or was the wrong one).
With the driver in "ATA/ATAPI/MFM/RLL support (DEPRECATED)" it worked for me.
So check if you really have the correct driver for your SATA-controller compiled in or try the deprecated driver.

I have an nvidia motherboard and disabling the nvidia driver under
“Serial ATA and Parallel ATA drivers” stopped machine from booting with
a kernel panic, good, I am pretty sure therefore that it’s the correct
driver.

I tried replacing it with the deprecated drivers, but wasn’t sure which
one to enable—I enabled all the generic looking ones, but couldn’t see
any kind of nvidia driver. What should I be looking for?

Thanks.

Could you perhaps post your output from "lspci -v" from the crux-install
cd? Should help us figure out what driver you need.
