Hi Alan,

Worried about ext3 pb, I try to merge parisc kernel 2.4.20-pa14 with 2.4.21-pre1.
This merge seems to works fine on a b180l+ (without pci devices).
But still boot twice (??) and crash on a b2k with an ide cdrom.

So with k-2.4.20-pa14 here is the ide cdrom identification:
...
Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
NS87415: IDE controller on PCI bus 00 dev 70
NS87415: chipset revision 3
NS87415: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0x0900-0x0907, BIOS settings: hda:pio, hdb:pio
    ide1: BM-DMA at 0x0908-0x090f, BIOS settings: hdc:pio, hdd:pio
hda: LTN485S, ATAPI CD/DVD-ROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 103
hda: ATAPI 48X CD-ROM drive, 120kB Cache
Uniform CD-ROM driver Revision: 3.12
...

And now with k-2.4.21-pre1-pa-alpha:

...

Just have to explain that after previous 'hdc:pio, hdd:pio' it wait less
than a second then reboot and finaly crash as follow:

Well, I can try with this dump to use Thibaut 'dump_analyser.sh' but I doubt
to obtain relevant info because of the two successive kernel launch?

May be can you advise me on a start point of investigation: it is the first
time I met this kind of two successive boot?

Thanks in advance for your attention,
    Joel


PS1: I join a full log including a normal 2.4.20-pa14 boot, the abnormal
2.4.21-pr1 crash and finaly the pim info.
PS2: it is a 32bits kernel build on a 'unstable' debian distro updated this
morning with gcc-3.0.4
