Since my two computers with USB are in transition, I tried out your new
kernel on the Gateway that does not do loop linux and it has an IDE zip
disk (hdd) and a pcmcia controller.
The kernel was a bit upset about the hdd not having a partition table, but
then it booted fine. Lots of stuff went by about SCSI system driver, and
host/usb-uhci.c (this has Intel USB, therefore uhci), and usb.c bus number
1, and USB Mass Storage Support Registered.
hub.c: New USB device .... address 2 (does this mean the controller is
scsusb.contro/bulk.msg timeout (what does this mean?)
scsi0: SCSI emulation for USB Mass Storage
I was able to mount /dev/sda1 /mnt
(or to cat /dev/sda1, which made a racket and put lots of garbage on the
I then cd'ed to dcim and its subdirectory, and as with DOS and SW91 there
are lots of jpgs there. I should have copied one as a test, but instead
I tried to view the photos. I typed zgv:
svgalib: zgv - mmap error in paged screen memory.
Then I tried Xvesa: can't establish listening socket.
Same thing with plain X and xinit.
So I soft rebooted with my usual BL2 kernel, which found hdd (IDE zip)
prefectly (the 2.4.31 kernel must not support that) and zgv put abstract
art on the screen, on all four terminals. I did not get a chance to try
Xvesa. I rebooted blind and then powered off and on again.
Now Xvesa and zgv are working again with the BL2 2.2.16 kernel.
What might be going on with this new kernel and video? It does not
interfere with mounting the memory card, but it would be nice to be able
to view photos without powering off and on again first. Is this some
sort of new bug in 2.4.31?
Could someone else check this out? Maybe with and without USB storage
device plugged in. Does it matter if USB is disabled in BIOS? uhci vs
