Hello linux-usb-users, I have linux box with one ALi M5237 (PCI USB 2.0) controller, and an external HDD enclosure attached to the USB controller. The kernel is 2.4.21-rc5. Here is my "lsmod" output: ------------------------------------------------------------------------ bongo:/# lsmod Module Size Used by Not tainted usb-storage 48704 0 sg 24324 0 (unused) ehci-hcd 15200 0 (unused) nls_iso8859-1 2880 1 (autoclean) sd_mod 10044 0 usbcore 54944 0 [usb-storage ehci-hcd] ide-scsi 8864 0 scsi_mod 52892 4 [usb-storage sg sd_mod ide-scsi] ------------------------------------------------------------------------ When I try to access the HDD in the enclosure(e.g. mount a partiton, list partiton table), some strange errors appear to my syslog: ------------------------------------------------------------------------ May 28 17:36:42 bongo kernel: SCSI disk error : host 1 channel 0 id 0 lun 0 return code = 70000 May 28 17:36:42 bongo kernel: I/O error: dev 08:03, sector 2 ------------------------------------------------------------------------ and the I/O error comes every time from different sectorm, and HDD access is very slow, and sometimes it freezes ... so, it looks like HDD error BUT I've tried few things:
1. i replaced my ALi M5237 with another ALi M5237 controller - the same result 2. i replaced my ALi M5237 with VIA VT6202 controller - everithing runs fine with the same modules/kernel 3. i put my ALi M5237 controller on Windows2000 - everityng works fine again. 4. using usb-ohci (for the "companion controller) instead of ehci-hcd it works again - slowly but works without errors Any ideas - where/what is the problem and how to solve it ? Thanks in advance ! -- Best regards, Pavel mailto:[EMAIL PROTECTED] ------------------------------------------------------- This SF.net email is sponsored by: ObjectStore.
