[parisc-linux] Tag starvation problem

[parisc-linux] Tag starvation problem

[alchemist]

Dear Sirs,

Since 2.4.20-pa35 my 712-60/128Mb suffers from the "tag starvation problem":

kernel msg: target(6.0) suffers from tag starvation problem

then everything seems ok for a few seconds and then a sudden kernel panic.
Note that until pa35 everything went ok (excluding the 712 power switch that
does not work).
I routinely use parisc-linux precompiled kernels.
The problem also appears in 2.4.21pa2.

any help anyone ?
thanks in advance.

I've been seeing problems with recent 2.4.x kernels in the SCSI error
recovery path on ia64-linux as well. I haven't tried to track down
those problems yet.
