I am testing -current on a ProLiant DL560 4P with 8.25 GB of RAM.
I have enabled PAE and SMP+APIC in my kernel config.
I initially had problems with the ciss and bge drivers, but Paul
Saab has added PAE support to those drivers and they have been
checked into CVS (Thanks Paul!).
I am now running into a reproduceable panic when doing a single
SSH session doing a "find . -print" on an NFS file share:
panic: kmem_malloc(4096): kmem_map too small: 96624640 total allocated
I tried lowering kern.maxvnodes from 536130 (default) to 200000,
but that did not alleviate the panic.
If anyone has any ideas of what might be the problem, please let
me know. I have attached a stack trace and some statistics
captured just before the panic that may be helpful.
Also, I get a different panic whenever mounting /dev/fd0:
root@bigdaddy:~> mount /dev/fd0 /mnt
panic: isa_dmastart: bad bounce buffer
