Summary 0000063: it87 has stopped working after upgrade to CentOS 5.5
Description After upgrading from CentOS 5.4 to 5.5, the it87 module fails to load:

(~): modprobe it87
FATAL: Error inserting it87 (/lib/modules/2.6.18-194.3.1.el5/kernel/drivers/hwmon/it87.ko): No such device

Removing and re-installing the module does not change anything

I have been using lm_sensors together with coretemp and it87 (all from ElRepo, latest versions) on the same machine without major issues.

 I can confirm that the current version of it87 from ELRepo does not get symlinked against -194 kernels.

 Just uploaded new versions:

x86:
kmod-it87-1.1-6.el5.elrepo.i686.rpm
kmod-it87-PAE-1.1-6.el5.elrepo.i686.rpm
kmod-it87-xen-1.1-6.el5.elrepo.i686.rpm

x86_64
kmod-it87-1.1-6.el5.elrepo.x86_64.rpm
kmod-it87-xen-1.1-6.el5.elrepo.x86_64.rpm

They should show up in the repo within the next hour.

Please note, version 1.1-6.el5.elrepo is only compatible with el5.5 series kernels (kernel-2.6.18-194.x) - users of older kernels should stick with version 1.1-5.el5.elrepo.

Tested here locally, but please confirm these packages are working for you.

 I have installed kmod-it87-1.1-6.el5.elrepo.x86_64. It did not create a symlink at all (I have 2.6.18-194.3.1).

 Yes, I see.

Can you just try uninstall/reinstall of the kmod just to make sure there's no weird updating issue going on.

What flavour kernel is it? RH/CentOS/SL?

These modules were built against a genuine RH -194.el5 kernel and my weak-linking is again against a genuine RH -194.3.1.el5 kernel.

I can test against a CentOS kernel later.

 I installed kmod-it87 on a SL5.5 box. It was all normal.

$ ls -l `find . /lib/modules -name it87.ko`
-rwxr--r-- 1 root root 78968 May 6 23:59 /lib/modules/2.6.18-194.3.1.el5/kernel/drivers/hwmon/it87.ko
lrwxrwxrwx 1 root root 46 May 18 12:22 /lib/modules/2.6.18-194.3.1.el5/weak-updates/it87/it87.ko -> /lib/modules/2.6.18-194.el5/extra/it87/it87.ko
-rw-r--r-- 1 root root 95720 May 18 09:01 /lib/modules/2.6.18-194.el5/extra/it87/it87.ko

Then, I uninstall kmod-it87 from the C5.5 machine and did a re-install.

$ ls -l `find /lib/modules -name it87.ko`

 OK, confirmed - I've just duplicated the problem.

The new kmod (1.1-6) is built against kernel 2.6.18-194.el5. When updating the previous version, the new version is correctly installed to:

/lib/modules/2.6.18-194.el5/extra/it87/it87.ko

but is *not* weak-linked against /lib/modules/2.6.18-194.3.1.el5

Uninstalling kmod-it87 and reinstalling fixes the issue.

 There is a wider issue here, and updating of kmod packages is universally broken.

When updating any kmod package on el5.5, no weak links at all are created.

Temporary workaround is to uninstall the old kmod then install the new package.

I'll file a separate bug.

 That "wider" issue was filed and fixed in bug 0000064.
