>Description:
As a result of what are assumed to be the recent changes to the ahc
driver code, when a FreeBSD 4.2-STABLE system is booted off
of Adaptec 2940U2W controller attached to a Infortrend IFT-3102
External Raid Controller kernel errors are seen at system boot
when the OS starts to mount filesystems. One error
will appear at startup for each host LUN as filesystems are mounted
So for two host LUNs two sets of errors will be seen on the
console at bootup. The exact output received is:
Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [kernel]...

These errors were repeated when the kernel was rebuilt using the GENERIC
config. 4.2-STABLE as of 1-08-2001 did not show these errors at startup.
Only after the system was updated to 4.2-STABLE as of 2-18-2001 to fix
the security vunerability in FreeBSD-SA-01:24 did this problem manifest
itself.
>How-To-Repeat:
Install/run 4.2-STABLE (>11-18-2001) on a IFT-3102 RAID controller.
At the start of filesystem mount kernel errors related to ahc
SCB's.
>Fix:
Apply the following patch to /usr/src/sys/cam/cam_xpt.c which adds a
quirk entry for the IFT-3102 to limit the number of tags to use to the
controller default of 32 per host LUN:
84a385,396
> /*
> * Infortrend IFT-3102 has a global host scsi channel
> * configuration paramater that determines the maximum
> * number of tags that each host lun (logical drive
presented
> * by the raid controller to the host controller)
> * can handle. By default this is 32 tags per lun.
> */
> {
> { T_DIRECT, SIP_MEDIA_FIXED, "IFT", "3102", "*" },
> /*quirks*/0, /*mintags*/2, /*maxtags*/32
> },
>
Another possible workaround is to try to increase the number of tags per
host
LUN to 255, but this might have other adverse affects on controller
performance. I didn't test this as this controller handles 4 production
systems with two different OSes (FreeBSD and NT) and I cannot risk stability
problems on these other systems.
