Description Vasily Averin 2007-07-16 06:28:27 UTC
Description of problem:
smp and hugemem kernels hangs or tried to access beyond end of device on the
nodes with more than 4Gb memory and LSI Logic MegaRAID SATA RAID Controllers
(150-4 or 150-6).

I've reported about this issue in RHEL4:
LSI Logic MegaRAID SATA RAID Controllers (150-4 and 150-6) are not works
correctly if more than 4 GB memory installed on the node. According to Ju
Seokmann this hardware is not supported 64 bit DMA.

However this issue is still not fixed in RHEL5 kernels, the following patch has
been lost:
