Hi, All when I write data to USB general serial, sometimes encounter the problem "scheduling while atomic" problem, and it is very similar with this: http://kerneltrap.org/mailarchive/linux-usb/2010/4/6/6259986 and I also find there is a patch: http://marc.info/?l=linux-usb&m=126405382220848&w=2 my kernel is 2.6.32. now with kernel 2.6.38, I find this patch wasn't applied. so , is the problem resolved? can anyone give me an advice?
