I installed 5.4-RELEASE on an old IBM PL300 yesterday, and while -RELEASE worked, updating to and booting a -STABLE kernel doesn't. The system locks up hard during boot at this point (verbose messages follows) isa0: <ISA bus> on isab0 atapci0: <Intel PIIX4 UDMA33 controller> port 0x376,0x170-0x177,0x3f6,0x1f0-0x1f atapci0: Lazy allocation of 0x10 bytes rid 0x20 type 4 at 0 7 at device 2.1 on pci0 ata0: channel #0 on atapci0 atapci0: Reserved 0x8 bytes for rid 0x10 type 4 at 0x1f0 atapci0: Reserved 0x1 bytes for rid 0x14 type 4 at 0x3f6 ata0: reset tp1 mask=03 ostat0=50 ostat1=00 ata0-master: stat=0x50 err=0x01 lsb=0x00 msb=0x00 ata0-slave: stat=0x50 err=0x01 lsb=0x00 msb=0x00 ata0: reset tp2 stat0=50 stat1=00 devices=0x1<ATA_MASTER> ata0: [MPSAFE] ata1: channel #1 on atapci0 atapci0: Reserved 0x8 bytes for rid 0x18 type 4 at 0x170 atapci0: Reserved 0x1 bytes for rid 0x1c type 4 at 0x376 I presume that this means -RELEASE liked my CD-ROM drive, while -STABLE doesn't (primary master is the HDD, secondary master is the CD-ROM) Any way I can work around this? - Julian -- [ Julian C.
