Ok, just to add to the original email - the system has been stable since I rebooted a couple of days ago, until this morning when I got the following: Jun 17 08:47:41 acid kernel: BUG: unable to handle kernel paging request at virtual address 0000f1e8 Jun 17 08:47:41 acid kernel: printing eip: Jun 17 08:47:41 acid kernel: *pde = 00000000 Jun 17 08:47:41 acid kernel: Oops: 0000 [#1] Jun 17 08:47:41 acid kernel: SMP Jun 17 08:47:41 acid kernel: CPU: 0 Jun 17 08:47:41 acid kernel: EIP: 0073:[<0808a542>] Not tainted VLI Jun 17 08:47:41 acid kernel: EFLAGS: 00010282 (2.6.21 #2) Jun 17 08:47:41 acid kernel: EIP is at 0x808a542 Jun 17 08:47:42 acid kernel: eax: 0814e008 ebx: 081cf060 ecx: 00000000 edx: 0814e008 Jun 17 08:47:42 acid kernel: esi: 00000000 edi: 081e3ef8 ebp: bfd6a9d8 esp: bfd6a9ac Jun 17 08:47:42 acid kernel: ds: 007b es: 007b fs: 0000 gs: 0033 ss: 007b Jun 17 08:47:42 acid kernel: Process get_listings.pl (pid: 10746, ti=c7e16000 task=c708c5d0 task.ti=c7e16000) Jun 17 08:47:42 acid kernel: EIP: [<0808a542>] 0x808a542 SS:ESP 007b:bfd6a9ac Seems to still be up and running at the moment.
