virtudude Posted September 11, 2009 Share Posted September 11, 2009 I'm having a problem that seems to be related to the amount of RAM I have. If I boot with 8GB installed and no boot options, I get this: /dev/diskXsY: Can't initialize disk cache This is followed by a failed attempt to fun fsck. It goes downhill from there. If I boot with maxmem=4096, everything works fine. Has anyone seen this before? The motherboard is a ga-ep45-ud3l. Oh, I'm also using the 32-bit kernel and extensions, if it matters. (VMware Fusion is making me) Link to comment Share on other sites More sharing options...

(VMware Fusion is making me) Is that the vanilla 10.0.0 kernel or a binary patched kernel for non-supported CPUs? I have the same issue with my Pentium D system running a binary hacked kernel.

I have the same issue with my Pentium D system running a binary hacked kernel. It's vanilla 10.0.0. I did some more research and it sounds like it might be related to the JMicron IDE controller on my board. I'm going to try disabling it when I get home, if possible.

I did some more research and it sounds like it might be related to the JMicron IDE controller on my board. I'm going to try disabling it when I get home, if possible. It was the JMicron controller. I disabled it in my BIOS and now everything works perfectly with the full 8GB. Link to comment Share on other sites More sharing options...
justroach Posted October 7, 2009 Share Posted October 7, 2009 Hrmmm... Having the exact same problem, but no JMicron controller to disable. My board (Intel SE7520BB2) has both a ICH5-RR and a SiL 3124 SATA interface. I get to the exact same "can't initialize disk cache" with both unless I boot to single user mode and manually mount the drive or boot with "maxmem=4096". Anyone have any ideas?

justroach Posted November 11, 2009 Share Posted November 11, 2009 Apparently I have a great habit of commenting on my own posts :/. Anyhoo, ran across the same problem on my Tyan S5397 recently after I accidentally added the -legacy kernel option to my com.apple.Boot.plist file... It gives me hope that there is something more going on here. I'll report back when I get back to the other MB. Link to comment Share on other sites More sharing options...
edmoncu Posted December 21, 2009 Share Posted December 21, 2009 my mobo has no jmicron but a marvell IDE controller. it is already disabled on the bios. im using an asus p5ql pro motherboard. im running a patched 10.6.2 with my celeron 420 processor.

edmoncu Posted December 21, 2009 Share Posted December 21, 2009 what kernel did you use? most, if not, ALL patched 10.6.2 mach_kernel are 32-bit only. 64-bit i believe is only offered on vanilla kernel. Link to comment Share on other sites More sharing options...
edmoncu Posted December 23, 2009 Share Posted December 23, 2009 if you're using a hacked kernel, you can try the '-force64' switch at the PCIEFI or Chameleon bootmenu. Link to comment Share on other sites More sharing options...
DariosF Posted January 11, 2010 Share Posted January 11, 2010 I have the same problem, but i have everything sata...in my bios there isn't jmicron option...My mobo is an asrocka770de+...With 4 gb of ram all is perfect, but when add 2 gb, snow leopard doesn't run... How i can resolve? Is possible bypass fsck control on startup? Link to comment Share on other sites More sharing options...

How i can resolve? Is possible bypass fsck control on startup? Same issue here when adding more than 4GB (Things are fine in Linux and ick Windows 7). I just installed an extra 4GB (total 8GB) and an extra PATA IDE drive (unfortunately both at the same time). I get the "manual fsck required" message on boot now. I can boot again with the "maxmem=4096" fix but now my Apple Ext Keyboard and Mighty Mouse are not recognized until I unplug and replug at the login screen. I'll try disabling my PATA drive next to see what happens since it's JMICRON I believe. This is Chameleon to vanilla 10.6.3 (well, with the Marvell driver added).

andrewc12 Posted May 8, 2012 Share Posted May 8, 2012 I had this issue too, except that I'm using the legacy_kernel iAtkos s3v2 uses for AMD Processors. I want to know if there is a permanent line that I can add somewhere so that the bootloader doesn't say 'fsck failed' and 'couldn't load disk cache'. I bott using the ModCD from nawcom (there fsck runs) Specs are: AMD Phenom X4 810 processor Mac OS X 10.6.3 iAtkos s3v2 Link to comment Share on other sites More sharing options...
