[parisc-linux] k-2.6.10-rc1-pa3 & c110: high data rate => Kernel panic - ...

[Joel Soete <soete.joel@tiscali.be>]

Hello James,

The serial console pb being fixed, I can now boot again my c110 with recent 2.6.10-rc1-pa3 :)

I do first a 'apt-get dist-upgrade' of the chroot disk which use lasi & 53c700 new driver and I unfortunately encounter numerous 
messages (error/warning?):

The apt-get operation was near complete:
just a pakage pakage failed to install, a quick check make me appear that postinst and postrm scripts were corrupted :(

But according to previous messages, should I doubt of the intergrity of this chroot disk or only those few files were corrupted?

Secondly the worst thing occured when I try a 'tar cslpf /chroot/Develop/linux-2.6.9-pa1.tar linux-2.6.9-pa1'
(the src linux tree standing on the internal disk using ncr driver and the target file standing on the external disk using 53c700 
driver):

numerous messages of style

ending by the fatal:
Kernel panic - not syncing: drivers/parisc/ccio-dma.c: ccio_alloc_range() I/O M.

And at the reboot weird kernel announce:

hmm, I try to reproduce the previous panic but I don't reach; this time only one:
  scsi1: (3:0) phase mismatch at 01e8, phase IO CD MSG BSY REQ MSG IN

Thanks in advance for your advise,
     Joel
