I pulled a 1Gb Jaz drive from another machine (I don't have any 2Gb jaz
drives) and tested that with my adaptec 1460.
I could scan the bus ok, but running /stand/sysinstall crashed the
machine. I got a crashdump;
panicstr: page fault
but I can't get any real information from this, no real stack trace :/
just late shutdown stuff;
(kgdb) where
#0 boot (howto=Cannot access memory at address 0xc8fe7c08.
) at ../../kern/kern_shutdown.c:304
(kgdb) list
299 EVENTHANDLER_INVOKE(shutdown_post_sync, howto);
300 splhigh();
301 if ((howto & (RB_HALT|RB_DUMP)) == RB_DUMP && !cold) {
302 savectx(&dumppcb);
303 #ifdef __i386__
304 dumppcb.pcb_cr3 = rcr3();
305 #endif
306 dumpsys();
307 }
308
Trying again after the reboot I can use the Jaz drive fine, sysinstall
works ok, I can mount the dos partition ... no scsi errors.
Unfortunately I don't have a 2Gb drive that WV said he was having
trouble with to test.
