https://bugzilla.novell.com/show_bug.cgi?id=266505 Summary: usb2 HD crash at reading of much data on a slow PC Product: openSUSE 10.3 Version: Alpha 3 Platform: i586 OS/Version: openSUSE 10.3 Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: susebugzilla@online.de QAContact: qa@suse.de Hello, I connected a TEAC HD-35PU Harddisk with 500GB in an external USB2 case to a 800 MHz PC. The Harddisk is recongnized and automatically mounted. Before starting the badblock command I unmounted /dev/sdc1 by hand. I started the command badblock -v /dev/sdc1 to simulate reading of a big amount of data. After badblocks red about 140MB following error message appeared 5 times in sequence in /var/log/messages : "Apr 20 10:08:00 suse10-3-alpha kernel: usb 5-6: reset high speed USB device using ehci_hcd and address 8" and the blue LED on the external USB2 HD remains blinking forever until switching off the external power supply. In /var/log/messages can be seen, that further automatic remounts of the harddisk have no success. I did this test again on a quicker PC with 2000 MHz CPU and suse10.0 (after inserting the Kernel Patch for the TEAC Drive from https://lists.one-eyed-alien.net/pipermail/usb-storage/2007-January/0027999....) and it run successfully over the whole 500GB. It seems, that some changes in the timing of the ehci_hcd driver might cause this problem on slower PC's.
