With the 2.4.x series of the kernel, in particular with RedHat's 2.4.9 kernel, 2.4.15, 2.4.16, and 2.4.17 I have been experiencing the same two problems. 1. the SCSI CD-ROM on my system works fine, that is until I mount the USB cf reader. After doing so, any attempts to mount a CD in the CD-ROM gives me the message "mount: wrong fs type, bad option, bad superblock on /dev/cdrom, or too many mounted file systems". If the CD-ROM is already mounted and I then mount the USB cf reader, the CD-ROM will no longer respond... unmounting and mounting the CD-ROM at this point seems to work but any attempt to access the information is futile. The physical eject on the CD-ROM also ceases to function after this. Tried removing all the USB modules followed by the SCSI modules and then modprobe them all again but doing that does not affect anything. Only way to access my CD-ROM again is a reboot of the machine. The wierd thing to this is, it does not affect my CD-R drive as it continues to work fine. This happens again if I were to repeat the above mentioned steps. 2. after mounting the USB cf reader, the shutting down of the system stalls for quite a bit at the point where it tries to unmount all the file systems. This occurs regardless of whether I unmounted the drive or not. Lastly, I know both the CD-ROM and USB cf reader are fine as they have worked fine under the later 2.2.x kernels, as well as in Windows. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
