Many systems within PIT for the snv_41 test run are failing with kmem corruption problems.
A type panic is:
kernel memory allocator:
buffer modified after being freed
modification occurred at offset 0xa0 (0xdeadbeefdeadbeef replaced by 0x30005bcc200)buffer=30002c86400 bufctl=30002d29308 cache: kmem_alloc_192
