Description Anil S Keshavamurthy 2004-04-06 10:21:07 UTC 
Distribution: 
Hardware Environment:Tiger4(IA64 platform)
Software Environment:linux kernel 2.6.5-rc2
Problem Description:can't rmmod processor.ko

Steps to reproduce: Compile the acpi processor driver as a module by having 
CONFIG_ACPI_PROCESSOR=m. And do insmod processor.ko and then rmmod 
processor.ko. The rmmod processor.ko panics the kernel thread which is 
performing rmmod.

getting removed without deleting proc entries.
