problem with all fedora2 update kernels, scsi, & usb

[Hans de Goede]

Nice to hear other people are having problems too,
please add your problem to:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=125887

Although this bug probably nees to be split into two:
-kernels > 2.6.5 (so 2.6.6 and up) freeze on athlons
-2.6 kernels have problems with aic7xxx scsi

Regards,

Hans
