Bug#386667: apcupsd: Causes kernel oops

[Peter Dey]

Package: apcupsd
Version: 3.10.17-2
Severity: critical
Justification: breaks the whole system

The kernel on my system has Oopses, on average, twice a month, since installing 
apcupsd.
In all Oops cases, apcupsd has been listed as the process in kern.log.

Since the instructions its oopsing on are fairly generic (sys_ioctl and 
exit_sighand), I'm guessing apcupsd is somehow 
managing to cause the oops...

 Since the instructions its oopsing on are fairly generic (sys_ioctl and

However, a kernel oops is always a kernel bug.  Given that apcupsd doesn't
contain any kernel modules, I'm reassigning this to the corresponding kernel
package.

I'm also lowering the severity, since from the kernel POV this bug doesn't
make the kernel unusable, it just makes it impossible to use apcupsd with
this kernel.

Cheers,

will forward this bug to apcupsd mantainer, maybe they have some clue 
about it .
