Full Discussion: After patching - ram decreased from 10 to 2 gb
Operating Systems Linux Red Hat After patching - ram decreased from 10 to 2 gb Post 302905272 by achenle on Tuesday 10th of June 2014 03:47:36 PM

If the question had memory switching between 4GB or 10GB instead of 2GB and 10 GB, I'd say someone loaded a 32-bit kernel non-PAE kernel instead of a 32-bit PAE-enabled or 64-bit kernel.

IIRC, a standard 32-bit Linux kernel can use 4 GB and a 32-bit PAE-enabled Linux kernel can use 16 GB.

I don't know of anything in Linux that limits memory to 2 GB. Though there might be something in older versions.

NAME

       bscv, bscbus, i2bsc - Blade support chip interface driver

DESCRIPTION

       The  bscv,  bscbus  and	i2bsc drivers interface with the Blade support chip used on Sun Microsystem's Blade server products. These drivers
       provide a conduit for passing control, environmental, cpu signature and event information between Solaris and the Blade support chip.

       These drivers do not export public interfaces. Instead they make information available via picl, prtdiag,  prtfru  and  related	tools.	In
       addition, these drivers log Blade support chip environmental event information into system logs.
