[OpenAFS] Redhat openafs crash

[Derrick J Brashear]

May  7 16:40:04 hjcl01 kernel: EIP is at osi_Panic
[libafs-2.4.18-24.8.0smp.mp]
0x20 (2.4.18-24.8.0smp)

tells us it told you something when it died. what did it say?

(osi_Panic is "printk a string and force an Oops", effectively)

you should also tell us how you configured the memcache.
