Re: Regular kernel panics

I've seen this on both RHEL 3 & 4.  I have only the following to offer:

[<c01e6679>] __delay+0x9/0xa
[<c0120eba>] panic+0x13b/0x13d
[<c0171756>] nr_blockdev_pages+0x6f/0xfa
[<c014c776>] si_meminfo+0x1f/0x3b
[<e0a7ed7b>] update_defense_level+0xf/0x332 [ip_vs]
[<c011c4a0>] activate_task+0x53/0x5f
[<e0a7f09e>] defense_timer_handler+0x0/0x29 [ip_vs]
[<e0a7f0a3>] defense_timer_handler+0x5/0x29 [ip_vs]
[<c012b58f>] run_timer_softirq+0x1eb/0x2d4
[<c02b5f1f>] net_rx_action+0x59/0xc1
[<co126781>] __do_softirq+0x35/0x79
[<c010934c>] do_softirq+0x46/0x4d
=======================
[<c0108910>] do_IRQ+0x2b3/0x2bf
[<c03115c0>] common_interrupt+0x18/0x20
[<c0171464>] bdev_clear_inode+0xb8/0x14b
[<c01859c4>] clear_inode+0xcc/0x102
[<c0187460>] generic_delete_inode+0xf8/0x229
[<c018787e>] iput+0x5f/0x61
[<c01726d3>] blkdev_put+0x249/0x254
[<c0168231>] __fput+0x55/0xee
[<c016823a>] filp_close+0x59/0x5f
[<c031147b>] syscall_call+0x7/0xb
[<c031007b>] rwsem_down_read_failed+0x167/0x204

which is strikingly similar to the dump from:

I was trying Fedora Core earlier, I may have to go back to it.
