I get this messages every few seconds in my ART kernel log:
BUG: sleeping function called from invalid context at include/linux/pagemap.h:165

Probably acpi related (power saving mode), you can try turning that off by setting acpi=off in the kernel boot parameters.

I think it is off, or where can I find this parameters?

you turn it off in grub.conf, on the kernel line. Add this to the end:
acpi=off

Just to make sure: (I have to add the RED part)
OLD Line:
kernel /vmlinuz-2.6.23.1-3.art ro root=/dev/VolGroup00/LogVol00
selinux=0
NEW Line:
kernel /vmlinuz-2.6.23.1-3.art ro root=/dev/VolGroup00/LogVol00
selinux=0 rhgb quiet acpi=off
Reboot, problem solved?

After the reboot, I recieved the same error:
The line in the grub.conf is now:
kernel /vmlinuz-2.6.23.1-3.art ro root=/dev/VolGroup00/LogVol00 acpi=off
in message log:

Hello,
I'm having the same problem.
I have just installed ASL a week ago in a RHEL5 ES server, with Plesk 8.2.
My server is freezing twice a day.
First apache stops, and if I don't reboot the server, everything stops.
I have several entries like this in the /var/log/messages file:
Feb 14 10:58:01 rhel5 kernel: BUG: sleeping function called from invalid context at include/linux/pagemap.h:165
Feb 14 10:58:01 rhel5 kernel: in_atomic():1, irqs_disabled():0
Feb 14 10:58:01 rhel5 kernel: [<c146856c>] [<c146ae3d>] [<c1420c43>] [<c1421084>] [<c1455ea6>] [<c1420c43>] [<c161b8e5>] =======================
I have tried the noacpi and acpi=off grub parameters, but it didn't work.
If I try to use the default RHEL5 ES kernel, I end up with lots of apache processes consuming all CPU (it looks like ASL doesn't work well without ASL's kernel)
After an apache crash, I can find some error logs in the /var/log/messages file:
Feb 14 10:39:38 rhel5 kernel: grsec: From 189.12.230.249: failed fork with errno -12 by /usr/sbin/httpd[httpd:30666] uid/euid:48/48 gid/egid:48/48, parent /usr/sbin/httpd[httpd:9241] uid/euid:0/0 gid/egid:0/0
Feb 14 10:39:56 rhel5 kernel: grsec: From 189.12.230.249: failed fork with errno -12 by /usr/sbin/httpd[httpd:26633] uid/euid:48/48 gid/egid:48/48, parent /usr/sbin/httpd[httpd:9241] uid/euid:0/0 gid/egid:0/0
This is a critical situation, I'll have to remove ASL soon If I didn't fix this problem. The server Uptime is very slow this month.
Thank you.
Alexandre

The line in the grub.conf is now:
kernel /vmlinuz-2.6.23.1-3.art ro root=/dev/VolGroup00/LogVol00 acpi=off
(then reboot)
Worked for me, the messages is only comming back one time right after the reboot...
Another option

If that doesnt work, try it noapic instead.

You mean:
kernel /vmlinuz-2.6.23.1-3.art ro root=/dev/VolGroup00/LogVol00 noapic
instead of
kernel /vmlinuz-2.6.23.1-3.art ro root=/dev/VolGroup00/LogVol00 acpi=off
Is it possible this make a difference?

Hello,
Neither option worked, the kernel bug messages are still there.
I'm confused, are these two parameters related to the same matter?
http://www.linuxquestions.org/questions ... rs-454675/
Despite of these messages, I'm not sure they are the source of the problem. It seems to be related to apache.
Using the server-status page I can see several pages in the "W" (Sending Reply) state for a long time (four hours).
It looks like these requestes stays there until the server crash.
Thank you.
