HP Smart Array controller, E200 family

Situation

A message ERROR: kernel: cciss: fifo full is being logged frequently.


Resolution

Update the kernel.

This issue is fixed as of kernel 2.6.5-7.286 and a fixed kernel is included in SLES9 Service Pack 4 and NLD9 Service Pack 4.

Additional Information

The messages are annoying, but harmless.

In kernels prior to 2.6.5-7.286, the kernel incorrectly assumed that the E200 family supports up to 1024 commands like most other Smart Array controllers where in fact it only supports up to 128 commands. As of2.6.5-7.286, a patchcciss-fifo-full.patch
has been included which corrects this.
