Kernel 2.4.20-13.7 breaks SDDR-31 USB CF reader

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003 Description of problem: I have an RH 7.2 that I just fully updated to current. It has a SanDisk SDDR-31 compact flash reader on it. This reader used to work with the previous kernel (2.4.9-34, I think) - I used it for a year or two with the old kernel. With the latest kernel that up2date installs for RH 7.2,(2.4.20-13.7), I get: Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0 SCSI device sda: 96385 512-byte hdwr sectors (49 MB) sda: Write Protect is off sda: sda1 usb-uhci.c: interrupt, status 3, frame# 1383 usb_control/bulk_msg: timeout At the user level, the mount /mnt/flash command completed, but cp /mnt/flash/* wherever/ just hung. Rebooted several times and it always failed this way. Let me know if there is any debugging info needed. Version-Release number of selected component (if applicable): kernel-2.4.20-13.7 How reproducible: Always
I'm told there aren't significant changes between the 2.4.20-13.7 kernel for RH 7.2, and the 2.4.20-13.9 kernel for RH 9, at least in the USB area. Nevertheless, I took this reader over to my RH 9 system, and it worked perfectly there. Copied off all files, no hangs or error messages. So maybe there are more changes in -13.9 than you think.
No, there aren't any differences among .[789], but the usb-uhci is a little too rude to some chipsets in -13 due to misguided VIA workarounds. Please try 2.4.20-18 (2.4.20-18.7 in your case).
Created attachment 92146 [details] dmesg output mounting /mnt/flash with kernel 2.4.20-18.7 Here is the dmesg output with kernel 2.4.20-18.7. The user command executing was mount /mnt/flash. The command hung. Note that with the -13.8 kernel, the mount command would work, but copying files off the CF card would hang after a few files had been copied.
End of lifed since Jan 1st. No further updates for RHL7/8 Can you repeat this with RHL9 and the latest errata kernel ? If so, please reopen.
