4gb seg fixup errors on Debian Lenny Xen domU
I run CompleteFusion, and several other sites, on a virtual server hosted at VPSLink. Recently, I upgraded the server from Debian Etch to Lenny. After the upgrade, I've noticed errors like the following in the output from dmesg:
4gb seg fixup, process imap-login (pid 29663), cs:ip 73:002d9226
printk: 121 messages suppressed.
Some basic investigation revealed that this is apparently a fairly common issue with Xen domU instances, but it should be easy to fix:
- First, make sure libc6-xen is installed: apt-get install libc6-xen
- If /lib/tls exists on your system (it didn't on mine): mv /lib/tls /lib/tls.disabled
- echo 'hwcap 0 nosegneg' > /etc/ld.so.conf.d/libc6-xen.conf && ldconfig
- Reboot your domU
