Hi!
If I boot Asus Eee PC with 8 Gb Transcend SDHC card inserted into the internal card reader, 2.6.25-rc7 prints the following:
[ 9.914968] scsi 2:0:0:0: Direct-Access USB2.0 CardReader SD0 0100 PQ: 0 ANSI: 0 [ 10.248951] sd 2:0:0:0: [sdb] 15660032 512-byte hardware sectors (8018 MB) [ 10.249695] sd 2:0:0:0: [sdb] Write Protect is off [ 10.249928] sd 2:0:0:0: [sdb] Mode Sense: 03 00 00 00 [ 10.249935] sd 2:0:0:0: [sdb] Assuming drive cache: write through [ 10.256632] sd 2:0:0:0: [sdb] 15660032 512-byte hardware sectors (8018 MB) [ 10.257440] sd 2:0:0:0: [sdb] Write Protect is off [ 10.257546] sd 2:0:0:0: [sdb] Mode Sense: 03 00 00 00 [ 10.257552] sd 2:0:0:0: [sdb] Assuming drive cache: write through [ 10.257657] sdb: sdb1 sdb2 sdb3 [ 10.259560] sd 2:0:0:0: [sdb] Attached SCSI removable disk [ 10.260489] usb-storage: device scan complete [ 10.380590] sd 2:0:0:0: [sdb] Result: hostbyte=0x00 driverbyte=0x08 [ 10.380590] sd 2:0:0:0: [sdb] Sense Key : 0x4 [current] [ 10.380590] sd 2:0:0:0: [sdb] ASC=0x11 ASCQ=0x0 [ 10.380590] end_request: I/O error, dev sdb, sector 15660024
As a result, no sdb device is created by udev.
If the card is inserted after the boot, it sometimes works fine (I've tested with "dd if=/dev/sdb of=/dev/null bs=512 skip=15660000"), and sometimes fails in the same way (the same I/O error message, dd hangs).
2.6.24.4 is fine (no problems at boot, always can dd read the whole card, all 15660032 sectors of it).
The other SD card I've got, 2 Gb, also works ok even with 2.6.25-rc7.
