Kernel 2.4.4, Adaptec 7880 on board controller

Kernel 2.4.4, Adaptec 7880 on board controller

[Joachim Backes]

Hi,

when booting on a machine having an Adaptec 7880 on board
controller (Kernel 2.4.4), then i get the following msg:

...
...

SCSI subsystem driver Revision: 1.00
request_module[scsi_hostadapter]: Root fs not mounted
request_module[scsi_hostadapter]: Root fs not mounted
request_module[scsi_hostadapter]: Root fs not mounted

...
...

The aic7xxx scsi driver is not configured as module,
but linked to the kernel.

1. Despite of this messages, my kernel is running without
   any problem.

2. No such msg when using 2.2.x kernels

3. No such msg with kernel 2.4.4, when using an Adaptec 29xxx
   controler.

Any idea?

Regards


Joachim Backes

This was fixed post v6.1.5 of the aic7xxx driver.  You
can obtain patches for the latest version from here:

Hmmm, I observe similar messages when
- scsi low-level driver (eg. sd, sr, st) linked to the kernel,
- no appropriate (corresponding to any of the above drivers) devices found
  on the hostadapters which have support linked to the kernel.

I don't think it is driver-specyfic. As I looked at the code it would be
difficult to avoid them (unless a linked-to-the-kernel function is able
to detect whether it is called from __init code or from a module
initialization code).
