>Description:
I removed the battery from my laptop while it was running, then put it back in the laptop. Kernel fall down go boom (panic). First happened while I had Xorg+KDE running. Panic occurred immediately, probably from KLaptopDaemon as I didn't have any terminal windows open. Secondary test to confirm the issue was done without Xorg, running "acpiconf -i batt".
Fatal trap 18: integer divide fault while in kernel mode
cpuid = 0; apic id = 00
instruction pointer
stack pointer = 0x20:0xc0ecc472
frame pointer = 0x28:0xe3217ba0
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 936 (acpiconf)
trap number = 18
panic: integer divide fault
>How-To-Repeat:
While laptop is on, remove the battery, reinsert the battery, and get battery information.
