Classification: openSUSE Product: openSUSE 11.4 Version: Factory Platform: x86-64 OS/Version: openSUSE 11.4 Status: NEW Severity: Critical Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: vrnb05@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:2.0b12) Gecko/20110222 Firefox/4.0b12 Hi, I am using OpenSuse 11.4 distro on Intel's I7 processor and motherboard. It doesnot have onboard serial port, hence we are forced to use USB to Serial converter. There is no error codes that gets displayed on screen. I am connecting through /dev/ttyUSB0 using PL203 driver. When i connect this to my hardware's console, and then execute 'find /' from my hardware's terminal, i get intermittent output thrown on minicom. As and when do keypress or move a mouse pointer it throws up a screenful of output before it stops. Again i have to keep moving either mouse/do key presses on keyboard to get the console output from my hardware. I am unable to get contineous console output of my hardware(logs). On further experimatation, I have found that it doesnot look to be a minicom issue here. I tried using 'screen /dev/ttyUSB0 115200' and 'putty' (for linux) both are showing the same erratic behaviour mentioned above. My tty configuration as optained from stty is as below: root# stty -a -F /dev/ttyUSB0 speed 115200 baud; rows 0; columns 0; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 5; -parenb -parodd cs8 -hupcl -cstopb cread clocal -crtscts ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr -icrnl -ixon -ixoff -iuclc -ixany -imaxbel -iutf8 -opost -olcuc -ocrnl -onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 -isig -icanon -iexten -echo -echoe -echok -echonl -noflsh -xcase -tostop -echoprt -echoctl -echoke root# uname -a Linux srinirao 2.6.37.1-1.2-desktop #1 SMP PREEMPT 2011-02-21 10:34:10 +0100 x86_64 x86_64 x86_64 GNU/Linux Has anyone came across this issue ? Is there anything i am missing out here with either the ttyUSB0 or Kernel driver or configurations related to ttyUSB0 ? Should i upgrade/downgrade my drivers ?.

The fact is if i am using opensuse 11.4, i am not able to work i mean that i am unable to get continuous console output of my logs when using minicom. so can please tell like what i can call this issue as ???? than telling error bug on opensuse 11.4. i hardly believe that this is error (bug) on opensuse 11.4 using i7 prosessor. please mention if any details you require, so that it can help everyone. thanks and regards varun -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I looked at the changes of PL2303 in-kernel driver between 11.3 and 11.4, and I'm curious if the newly implemented data carrier detect signal handling interferes with the data flow here. So I've prepared a test kernel that reverts this change. Would you be so kind as to test the kernel from http://download.opensuse.org/repositories/home:/LPechacek:/branches:/openSUS... and let us know if that makes your trouble go away, please? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
