From: Stefano Mangione <s.mangione@gmail.com> http://marc.theaimsgroup.com/?t=111989851700002&r=1&w=2 The device is seen, can be mounted and the filesystem listed, but file transfers run very slow, i guess they stop after a few KB. 2.6.11.12 works well. The device is a 256MB OTi Flash Disk, my USB host is listed as a VIA VT6202, the motherboard is an MSI with A6712VMS V1.9 072903 BIOS /sbin/lspci -n: 00:10.0 Class 0c03: 1106:3038 (rev 80) 00:10.1 Class 0c03: 1106:3038 (rev 80) 00:10.2 Class 0c03: 1106:3038 (rev 80) 00:10.3 Class 0c03: 1106:3104 (rev 82) ================================================================== From: Alistair John Strachan <s0348365@sms.ed.ac.uk> I get the same problem on an Intel laptop. Sometimes it works, sometimes it doesn't.
Do you mount the usb disk with the "sync" option? I can confirm the low performance (few KB/s instead of 5 MB/s with Kernel 2.6.11) when I mount with "sync". Without "sync" the performance seems to be fine although it is dangerous since it is a removable media. 2.6.11 does not show this behavior. Ralf
fatfs honors the 'sync' option since 2.6.12, and I had the (previously not working) 'sync' option in /etc/fstab, so I guess this bug should be rejected as INVALID
Yes, that is the case.
