Is there any way to get rid of these with the ahc driver?
I'm using an Adaptec 2940UW.
Previously, I had three TCQ (tagged-command-queuing) supporting
drives, with a ccd stripe between two of them. I never ever saw this
message.
Last night, I reconfigured with five TCQ supporting drives, with a ccd
stripe between four of them. I see this message just booting. I had
to build a kernel with TCQ turned off, to avoid frying my filesystems.
I have a NetBSD system at work that I have toyed around with that has
six TCQ drives, with a ccd stripe between five of them, and I never
see this happen there. Except it has three SCSI busses (a 2940 and a
3940 (dual)). Would more busses/controllers make a difference?
Is there some kind of kernel setting I can tweak to give it more
"buffers", or something, to make this go away? I remember Justin
Gibbs saying that this was one of the things he was going to fix in
his new, improved, driver model.
This is a stock NetBSD-1.2 system, FWIW.
