Hi all,
I have a mount problem which occurs only on the first try after a replug of
any available USB2.0 Memory Key.
The EHCI controller and USB storage drivers are from 2.4.32 kernel (Yes, I
know ;-)
Console output:
[EMAIL PROTECTED] root]# mount -t vfat /dev/sda1 /mnt/usbdisk/
I/O error: dev 08:01, sector 0
FAT: unable to read boot sector
mount: wrong fs SCSI device sda: 251904 512-byte hdwr sectors (129 MB)
type, bad optionsda: Write Protect is off
, bad superblock sda1 on /dev/sda1,
or too many mounted file systems
The second try always succeeds.
Replacing 'vfat' by 'auto' is always successful, even on the first try.
Something weird happens on the first READ_10 operation (see below).
Following is the dmesg output from unplug - replug - mount operations :
