Kernel panic on startup in 10.5.3

[alfonzotan]

I updated to 10.5.3 over the weekend, and my hackint0sh had been running fine until this morning (several power-down restarts since updating, no problems), when I got a recurrent kernel panic on startup. It's not that big of a deal, since I have a recent backup, but it'd still be nice to know what's going on. The system is about a year old, Asrock Conroe 1333. Original install of 10.5 was Kalyway 10.5.2 with the vanilla kernel. Here's what I scribbled down from the -v boot:

 

panic(cpu 1 caller 0x001A8CD4): kernel trap at 0x00197f9c, type 14=page fault, registers

 

... and at the end of the screen:

 

BSD process name correspond to current thread: syslogd

 

I didn't have time to sit there and troubleshoot, but I'll take a swing at it tonight. Any suggestions welcome. I'll be kind of surprised if it's something like bad RAM, as I said, this box has been running various osx86 installs without a hitch for nearly a year now.

Identical symptoms (same trap at address / type 14) in my site,

yet current thread "DirectoryService".

 

 

Env: Mac Pro 2.8Ghz (2 * 4 Cores), 2GB DDR2-800

 

I've tried:

 

(1) Move system HDD to another Mac Pro to do HDD-Repair and check

==> fsck_hfs found nothing bad, all checks were OK.

 

(2) Remove lower DIMM board(1GB DDR2-800) and keep upper DIMM board(1GB DDR2-800)

==> Successfully boot into system.

 

(2) Remove lower DIMM board(1GB DDR2-800) and keep upper DIMM board(1GB DDR2-800)

==> Successfully boot into system.

 

contd.

 

(3) Re-install the DDR2 piece in the lower DIMM board and put back lower DIMM board

back into Mac Pro box.

 

==> Well, system seemed to be OK again.
