Subject: 2.6.0-test4 - PL2303 OOPS - see also 2.4.22: OOPS on disconnect PL2303 adapter
Date: Tue, 2 Sep 2003 01:39:08 +0800 [thread overview]
Message-ID: <200309020139.08248.mhf@linuxmail.org> (raw)
PL2303 is used to connect the serial console on a classic serial port
of a test machine. HW nandshaking is used
The test machine reboots once a minute and dumps lots of messages
Frequently:
- driver hangs
- userspace (cu) can't be stopped
- pl2303 and/or usbserial can't be unloaded
- USB interrupts stop
- problems result in requiring a reboot.
- None of these problems seen before fixes such as "send break"
(which works) were made
- Feels like buffer heads get out of synch at times
- Changing Baudrates from 115200 to 38400 or 9600 has no effect
- It seems to be worse than ever even with oopses _now_ as it
has been used for many months and none were seen
- 2.4.21,22 behave essentially the same
Regards
Michael
