Hello, I have been using linux for a while now and I have noticed, over the past few months, that with the 2.4 test series and 2.3 series of kernels, that I have been having problems with what may be the vfat file system driver. Whenever I am running one of these kernels and I do some sort of large file transfer operation from one of my ext2 partitions to my windows (vfat) partition, I get strange behavior in X. If and only if I am running X, the screen immediately goes blank and remains blank until I move the mouse. Upon doing so, it continues to go blank unless I keep the mouse in constant motion. It is almost as if I have the blank screeen set up to start at 0 seconds or something. This behavior continues after the file transfer has completed and the only solution I have found to restore X functionality is to reboot the computer. I have noted this behavior in most of the 2.4 test kernels and most recently in the 2.4.0 kernel. I dont recall witnessing this behavior in the 2.2 series. I do have a VIA KA-7 motherboard, AMD Athlon 650 processor, and the following hdparm settings: hdparm -c 1 -d 1 -k 1 -m 8 -u 1 /dev/hda If there is any other information that I can supply you with that might help you in understanding this problem, please let me know. I have attempted to contact the maintainer of the vfat driver listed in the kernel documentation, but the email address is no longer active. Please send me a reply personally because I am not currently on the mailing list. thanks, Rodney M Jokerst - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
