I got a panic when booting with a kernel as of today. Right before the
panic, I get "ata1-slave: TIMEOUT in ATAPI_IDENTIFY retrying, 3 tries left
LBA=0". Note that on the ata1 channel, I only have one device (a CDROM,
a master).
It works fine with a kernel as of Dec 30. The panic msg is a read on page
not present. I'm guessing the atadev or param pointers are invalid.
Here is the call stack:
(gdb) l *ata_getparam+0xb6
0xc045d716 is in ata_getparam (../../../dev/ata/ata-all.c:585).
580 break;
581 request->retries--;
582 }
583 ata_free_request(request);
584 }
585 if (!isprint(atadev->param->model[0]) ||
586 !isprint(atadev->param->model[1]))
587 error = ENXIO;
588 if (error) {
589 free(atadev->param, M_ATA);
(gdb) l *ata_identify_devices+0x5f
0xc045d8ff is in ata_identify_devices (../../../dev/ata/ata-all.c:637).
632 else
633 ch->device[SLAVE].attach = ad_attach;
634 #endif
635 }
636 if (ch->devices & ATA_ATAPI_SLAVE) {
637 if (ata_getparam(&ch->device[SLAVE], ATA_ATAPI_IDENTIFY))
638 ch->devices &= ~ATA_ATAPI_SLAVE;
639 else {

738 for (ctlr=0; ctlr<devclass_get_maxunit(ata_devclass); ctlr++) {
