Slow transfer rates in a Thinkpad R52
by Arturo Alejandro Hoffstadt Urrutia
Hello:
I have a Lenovo/IBM Thinkpad R52. It is a Celeron 1.4 Ghz, 256 RAM, Intel 915
video, sata hdd 40 GB, DVD-CDRW, etc.
The thing, is that when I transfer files from the/to the CDrom, the whole
system (even the mouse) gets really slow.
This is the model of my sata controller reporte by lspci:
Intel Corporation 82801FBM (ICH6M) SATA Controller (rev 03)
Another thing, is that the hdparm program, can't change the UDMA settings. It
says that my drives doesn't have udma, but it really has.
[root@localhost ~]# hdparm -c /dev/sda
/dev/sda:
IO_support = 0 (default 16-bit)
[root@localhost ~]# hdparm -c1 /dev/sda
/dev/sda:
setting 32-bit IO_support flag to 1
HDIO_SET_32BIT failed: Invalid argument
IO_support = 0 (default 16-bit)
Also, when the system start using swap, it start to slow (a lot, but not as
much as when I read/write from/to the CDrom).
This is the list of the modules I found relevant from lsmod:
i2c_i801 11853 0
i2c_core 25537 2 i2c_ec,i2c_i801
ide_cd 42337 2
cdrom 38625 1 ide_cd
ahci 23365 0
ata_piix 17993 3
libata 102745 2 ahci,ata_piix
sd_mod 24897 20
scsi_mod 138601 4 sg,ahci,libata,sd_mod
ext3 135497 1
jbd 63081 1 ext3
ehci_hcd 35533 0
ohci_hcd 25181 0
uhci_hcd 27725 0
I hope someone can help me... I couln't find the problem...
See ya!
PS: I will send transfers rates under determined actions later...

Problems with CD-RW/DVD and USB
by Erick Muller
Hi list, I have serious problems with my CD-ROM reader and my USB, I
think all due to the Automount function, I don't know what happened but
suddenly they don't work anymore I only put new devices and that's
all... I know this sounds very weird but is true. At first I thought I
was wrong when I change from a CD-ROM to another and simply didn't work,
but today it happened the same with my USB device, this time I even
can't charge my iPod it appears like the USB is death. I don't know what
to do. My laptop is an IBM Thinkpad R51 and I use Core 5 and kernel
2.6.18-1.2239.fc5 (I tried updating the kernel but the only thing that
change is that the messages don't appear now using dmesg, only when I
use kernel 2.6.15-1.2054_FC5)
The results from dmesg | tail are:
For the CD-ROM thing:
ATAPI device hdc:
Error: Not ready -- (Sense key=0x02)
No reference position found (media may be upside down) -- (asc=0x06,
ascq=0x00)
The failed "Read Cd/Dvd Capacity" packet command was:
"25 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 "
For the USB:
usb 4-4: new high speed USB device using ehci_hcd and address 53
usb 4-4: new high speed USB device using ehci_hcd and address 55
usb 4-4: new high speed USB device using ehci_hcd and address 56
usb 4-4: new high speed USB device using ehci_hcd and address 106
usb 4-4: new high speed USB device using ehci_hcd and address 110
usb 4-4: new high speed USB device using ehci_hcd and address 118
usb 4-4: new high speed USB device using ehci_hcd and address 125
usb 4-4: new high speed USB device using ehci_hcd and address 4
usb 4-4: new high speed USB device using ehci_hcd and address 33
usb 4-4: new high speed USB device using ehci_hcd and address 42
Thank you very much, I hope someone could help me as I'm really
desperate

Hibernate on FC-6 (partly) fails
by Gianluca Sforna
Sorry for the cross posting (I can't really decide which list was better...)
I'm seeing this regression (compared to FC-5, where it used to work
fine) on the hibernate function with this laptop, an ASUS M6Ne
(Centrino 1.7Ghz, 512Mb RAM, ATI mobility radeon 9700, _not_ using any
proprietary kernel modules)
Basically, the hibernate procedure go as far as the "shutting down
hda" message, then fails to turn off power.
I am forced to turn it off manually. Otherwise the operation seems working.
Anyone else with similar symptoms?
Moreover, I saw from time to time a screen of kernel error messages (
a stack trace ?) on the consule during wake up operation, but I am not
sure if this was generated during hibernation.
I will try to find a pattern for this and eventually post agina more details.
Cheers
