I'm having a problem with booting off a disk on an AS500/266. srm_disk's bd_open() function is failing on the first call because lp->d_magic != DISKMAGIC. I've found that if I alter bd_open to ignore this & continue on, things work just fine. Successive calls to bd_open in the same bootup have no problems with the label. This is on both warm & cold boots. I've tried inserting both delay()'s & memory barriers after the call to bd_strategy(). Somebody's borrowed my copy of the Alpha architecture handbook, so I'm flying blind here... I should mention that I've also re-installed the disklabel using FreeBSD's /sbin/disklabel & FreeBSD's boot1 (label was initially installed with Digital UNIX 4.0.). Neither the kernel, nor the FreeBSD /sbin/disklabel nor the Digital UNIX /sbin/disklabel has any problem with the disklabel's magic number. I've appended output from a cold boot in case anybody has any ideas.
