Description paluch 2000-04-16 17:55:41 UTC 
The kernel (from RedHat 6.1 and 6.2) locks up on boot if these two
conditions are met:
1) compiled in SCSI streamer support
AND
2) There is defined
   #define RELOAD_FIRMWARE         1
   in qlogicisp.c (defined as default on standard kernels)

The lockup occurs on SCSI devices detection (right before attempt
to detect the streamer).

The problem did not appeared in RedHat 5.2 kernel, because there was
not compiled in streamer support (in Alpha version of kernels).

Solution: Do not #define RELOAD_FIRMWARE 1

Here is a log of a typical boot:

Comment 1 Doug Ledford 2000-04-22 05:11:59 UTC 
The default Red Hat kernels on the Alpha (as of 6.2 anyway, I didn't have
anything to do with the 6.1 Alpha kernels) do not have the st module compiled
into the kernel, but as a separate module.  Are you seeing this problem on
custom compiled kernels or on the Red Hat supplied kernels?
