serial console handling changed in 2.6.16-1?
Hi
I am trying to figure out why the mini.iso (2.6.16-1 kernel) I tried
to install yesterday on my Xserve G5 hung. The last log entries
printed before the hang were:
.
.
.
Dquot-cache hash table entries: 512 (order 0, 4096 bytes)
Initializing Cryptographic API
io scheduler noop registered
io scheduler anticipatory registered (default)
io scheduler deadline registered
io scheduler cfq registered
HVSI: registered 0 devices
Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled
pmac_zilog: 0.6 (Benjamin Herrenschmidt <benh@kernel.crashing.org>)
pmac_zilog: Error registering serial device, disabling pmac_zilog.
pmac_zilog: Did another serial driver already claim the minors?
Trying to im_free nonexistent area (d0000800820d7000)
With the last daily image (2.6.15-1 kernel), which *DOES* boot, there
is no mention of 'Trying to im_free' anything, nor is there a
pmac_zilog error. Here is the section of the log file from the
2.6.15-1 boot, continuing past the pmac_zilog stuff:

Dquot-cache hash table entries: 512 (order 0, 4096 bytes)
Initializing Cryptographic API
io scheduler noop registered
io scheduler anticipatory registered
io scheduler deadline registered
io scheduler cfq registered
HVSI: registered 0 devices
serial8250_init: nothing to do on PowerMac
pmac_zilog: 0.6 (Benjamin Herrenschmidt <benh@kernel.crashing.org>)
ttyS0 at MMIO 0x80013020 (irq = 22) is a Z85c30 ESCC - Serial port
ttyS1 at MMIO 0x80013000 (irq = 23) is a Z85c30 ESCC - Serial port
.
.
.
It seems to me that I should not be getting the pmac_zilog error about
registering the serial device.
Has something changed in the way the serial console is handled between
these two versions?
Thanks,
Toni
