Hi All, I upgraded from RH9 to FC2, and I have a problem with the scsi subsystem. When I try to load a module that uses the scsi subsystem it fails due to an unknown symbol in the modules: --- [root@amd /etc]# modprobe usb-storage WARNING: Error inserting scsi_mod (/lib/modules/2.6.5-1.358/kernel/drivers/scsi/scsi_mod.ko): Unknown symbol in module, or unknown parameter (see dmesg) WARNING: Error inserting scsi_mod (/lib/modules/2.6.5-1.358/kernel/drivers/scsi/scsi_mod.ko): Unknown symbol in module, or unknown parameter (see dmesg) FATAL: Error inserting sd_mod (/lib/modules/2.6.5-1.358/kernel/drivers/scsi/sd_mod.ko): Unknown symbol in module, or unknown parameter (see dmesg) WARNING: Error inserting scsi_mod (/lib/modules/2.6.5-1.358/kernel/drivers/scsi/scsi_mod.ko): Unknown symbol in module, or unknown parameter (see dmesg) FATAL: Error inserting usb_storage (/lib/modules/2.6.5-1.358/kernel/drivers/usb/storage/usb-storage.ko): Unknown symbol in module, or unknown parameter (see dmesg) FATAL: Error running install command for usb_storage [root@amd /etc]# dmesg scsi_mod: Unknown parameter `max_scsi_luns' scsi_mod: Unknown parameter `max_scsi_luns' sd_mod: Unknown symbol scsi_device_get sd_mod: Unknown symbol scsi_wait_req sd_mod: Unknown symbol scsicam_bios_param sd_mod: Unknown symbol scsi_block_when_processing_errors sd_mod: Unknown symbol scsi_register_driver sd_mod: Unknown symbol scsi_ioctl sd_mod: Unknown symbol scsi_device_put sd_mod: Unknown symbol __scsi_mode_sense sd_mod: Unknown symbol scsi_logging_level sd_mod: Unknown symbol scsi_release_request sd_mod: Unknown symbol scsi_allocate_request sd_mod: Unknown symbol scsi_io_completion sd_mod: Unknown symbol print_sense sd_mod: Unknown symbol print_req_sense sd_mod: Unknown symbol scsi_set_medium_removal scsi_mod: Unknown parameter `max_scsi_luns' usb_storage: Unknown symbol scsi_report_device_reset usb_storage: Unknown symbol scsi_remove_host usb_storage: Unknown symbol scsi_host_put usb_storage: Unknown symbol scsi_scan_host usb_storage: Unknown symbol scsi_add_host usb_storage: Unknown symbol scsi_host_alloc [root@amd /etc]# --- 'rpm -V' shows that there aren't tampered with the kernel or the modules. Any hints? Best regards, Allan -- This message is transmitted on 100% recycled electrons.
