Larry & Team:

On the evm crash below, my previous assessment had been wrong.
Instead, the use of TAILQ_REMOVE() macro in this crashing case needs =
enhancement.
I will make the change and ask Jim K to review it.

Thanks.

g11r10 has an spm core only; it is crashing due to seg fault in =
spm_pollAddDevice() on a call to memcpy() where the source pointer is =
null.

on g12r10:
sdm_cfgd crash is a manifestation of the RMC problem documented in =
Defect 20580
eventd crash is a manifestation of the RMC problem documented in Defect =
20580
evm_cfgd crash is crashing due to seg fault in evm_delLunFromDiscList() =
in evm-db.c; looks like we're accessing a freed lunEntry pointer.

I'll take a look at g4r5 once I find out its IP address.

	One FP crash was definitely the spinlock crash, but the other is on the =
stand-alone system g4r5 which just had storage added to it and I have =
yet to create a volime.

	G11r10, g12r10 and g4r5 are all getting the eventd crash.

	G12r10 has the evm_cfgd and sdm_cfgd crashes as well.

	The FP crash may be related to the spin lock change that Max backed out =
today.
	What machines are the eventd / sdm_cfgd / evm_cfgd crashes on?
	Thanks.

		I loaded 3 cougar systems (1 2 node cluster and  1 standalone)  with =
//depot/dev/.@27286 and I am seeing crashes in eventd, sdm_cfgd, =
evm_cfgd and FP.
