I am getting the following kernel panic: 2.6.9-89.0.16.EL #1 Tue Nov 3 17:15:02 EST 2009 i686 i686 i386 GNU/Linux This system has ran fine for 2 years+.

System has 1 GIG ram, SATA disk running in RAID-1. /proc/mdstat shows everything is fine on the array.

It started to panic last week. I upgrade from 4.4 to 4.8 and same thing is still happening.

Looking back further in the messages I see this also: Nov 17 10:09:21 kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000108 Nov 17 10:09:21 kernel: printing eip: Nov 17 10:09:21 kernel: c014c9b8 Nov 17 10:09:21 kernel: *pde = 3a57a067 Nov 17 10:09:21 kernel: Oops: 0000 [#1] Nov 17 10:09:21 kernel: Modules linked in: md5 ipv6 autofs4 sunrpc ipt_REJECT ipt_state ip_conntrack iptable_filter ip_tables cpufreq_powersave dm_mirror dm_mod button battery ac uhci_hcd ehci_hcd snd_via82xx snd_ac97_ Nov 17 10:09:21 kernel: CPU: 0 Nov 17 10:09:21 kernel: EIP: 0060:[<c014c9b8>] Not tainted VLI Nov 17 10:09:21 kernel: EFLAGS: 00010206 (2.6.9-89.0.16.EL) Nov 17 10:09:21 kernel: EIP is at page_waitqueue+0x17/0x29 Nov 17 10:09:21 kernel: eax: 88200020 ebx: c1400020 ecx: 00000020 edx: 00000000 Nov 17 10:09:21 kernel: esi: c1400020 edi: 00000000 ebp: c1b34c00 esp: f0379e8c Nov 17 10:09:21 kernel: ds: 007b es: 007b ss: 0068 Nov 17 10:09:21 kernel: Process zcat (pid: 13339, threadinfo=f0379000 task=ecb6f1a0) Nov 17 10:09:21 kernel: Stack: c014c9d3 c1400020 fffd1a58 c015e1ad fffd4000 e0007000 62708f43 635c49ae Nov 17 10:09:21 kernel: c17279e0 00000000 e07a9a20 00296ae0 ee0ac9fc 00000001 c1b34c00 00296ae0 Nov 17 10:09:21 kernel: f03e4000 ee0ac9fc c015e41b 00000000 fffd1a58 f03e4000 00000000 c1b34c00

What might be happening here?
