SubjectUSB CF reader reboots PC
ASUS P4S533 (SiS645DX chipset)
P4 2GHz
1G PC2700 RAM
SanDisk SDDR-77 ImageMate Dual Card Reader (using only CF cards)

----------------------------
devfs compiled in to kernel, devfs=nomount in lilo.conf

Insert CF card. mount it. cd to it, do reads and/or writes
umount card. remove card.
insert a different card (does not happen if the same card is used)
mount it. system reboots. logs are corrupted

Doesn't happen every time for read - sometimes I can read 2 or 3 cards first
Happens every time for write - if I write to a card then changing cards
causes a reboot

----------------------------
devfs=mount in lilo.conf

Insert CF card.
ls /dev shows sda and sda1
mount it.
ls /dev shows sda - no sda1
cd to mounted CF card
process hangs, sd-mod & usb-storage "busy"
rmmod -f usb-storage or sd-mod causes PC to stop
(keyboard & mouse unresponsive, wmfire frozen, net disconnects)

reboot
Insert CF card.
ls /dev shows sda & sda1
mount it.
ls /dev shows sda - no sda1
umount it
ls /dev shows sda - no sda1
modprobe -r sd-mod && modprobe sd-mod
ls /dev shows sda & sda1
