2.2.15pre11 on PB Lombard

2.2.15pre11 on PB Lombard

[Derek Homeier]

Hi all,

has anyone got the latest kernel from paulus's stable tree running on
a 1999 powerbook? It panicks invariably after hda and hcd are initialized.
xmon tells the following:

Floppy drive(s): fd0 is 2.88M
Machine check in kernel mode (regsat c03fdd90)
caused by (from srr1): Unknown udm in srr1
                               ^^^<- not sure about this bit, my handwriting
                                     really leaves to be improved...:(

NIP: C00D0D54 XER:20000000 LR: C00D0D30 REGS: 03fdd90 TRAP: 0200
MSR: 00009030 [EEIRDRME]
TASK=c03fc000[1] 'swapper' mm->pdg c0162000 last syscall:120

... some 2^4 adresses or so follow, which I could write down if anyone
will find them useful. I can't get anything beyond that, because xmon
prints everything else black on black!

This happens both with CONFIG_MAC_FLOPPY set or unset (the above is without
floppy driver)

Grateful for any pointers,
							Derek

I have a 400MHz Lombard with 128MB Ram.

No panics for me.

Check that you didn't include inadvertently the legacy PC floppy driver

Hum... I should make sure not to enable interrupts when setting the disk
features... I'll fix that asap.

oops, I forgot to mention, that I boot using BootX version 1.1.1

Oh right, CONFIG_BLK_DEV_FD dunnit! I wonder how I came to include it, since
I usually start with pmac_defconfig and from that only remove stuff I don't
need, except for few things like the USB drivers. It boots, however, and
I even got the SUN12x22 font to work now, thank you!
What's still causing problems is the DMA code, however. There's still the

: hda: Enabling MultiWord DMA 2
: hdc: packet command error: status=0x51 { DriveReady SeekComplete Error }
: hdc: packet command error: error=0x54
: ATAPI device hdc:
:   Error: Illegal request -- (Sense key=0x05)
:   Invalid field in command packet -- (asc=0x24, ascq=0x00)
:   The failed "Start Stop Unit" packet command was:
:   "1b 00 00 00 03 00 00 00 00 00 00 00 "
: cdrom: open failed.

error on startup. I can't see if this is directly causing any problems, but
the performance for hdc is frequently down to 0.8 MB/s. Apparently ejecting
and reloading the disk is sufficient to bring it back to 1.6 MB/s, but after
returning from sleep it's down again (this is the 24X CD-ROM on a 333 MHz
PB 101, FYI). Well, at least I found an easy workaround now...

I also noticed that power consumption during sleep had dramatically increased
with the previous 2.2.15pre kernels; I'm currently checking out if that problem
persists.

Thanks again,
							Derek

Seems as it is still there, the battery is discharged by approx. 40% during
24 hours of sleep w/ 2.2.15pre11, while it used to be ~10%. I think it was
even more (>60%) with 2.2.15pre3-7. Has anyone else seen this?
The sound module was unloaded and the CD drive empty.
