two random thoughts- 1. can he try 32 bit kernel on same exact machine, just to rule out hardware problems?
2. is there a pattern to the timeouts, like always same number of errors before a good packet? allan On 5/26/08, Nicolas <nicolas.martin at freesurf.fr> wrote: > Sam V. posted recently a bug report with a 64 bits kernel, running the > pixma backend and a MF-4270 Canon MFP. > > Details here: > > > https://alioth.debian.org/tracker/?group_id=30186&atid=410366&func=detail&aid=310861 > > He has the pixma backend running fine with a 32 bits kernel (same > version as 64 bits) in same conditions. > > On a 64 bits 2.6.25 kernel (Fedora 9) or 2.6.24 (Ubuntu), the logs show > that sometimes (but not always, that's why scanning finally works, but > takes very long time), there appears to be a: > > "Resource temporarily unavailable" > > error for read calls, from either sanei_usb_read_int() or > sanei_usb_read_bulk().
