Description of problem:
After upgrading from RH8 to RH9, my GCE-8520B cd writer connected via USB 2.0
started freezing in the middle of burns when using cdrecord. There is no apprent
pattern to when during the burn the freeze occurs, save that it always happens
during the write and not during fixation. If I wait long enough (several
minutes), cdrecord returns the following error message:
faio_wait_on_buffer for writer timed out
but never exits itself. There are no other error messages that I've found,
neither in /var/log/messages, nor in dmesg.
After some experimentation, I found that the following combinations of stock
kernels and cdrecord versions work, indicated by plusses:
cdrecord 2.0-6 1.10-14
2.4.18-27.8.0 + +
2.4.20-9 - +
When using the older cdrecord with the newest kernel, the same error message
appears when cdrecord exits, but burns appear to work fine.
I'm invoking cdrecord like this:
cdrecord -v driveropts=burnfree speed=52 dev=0,0,0 -data some.iso
I've tried writing isos of different sizes, and with the same results, so it's
not the particular iso I'm trying to write, nor is it the hardware since it
appears to be functional. Moreover, I've attempted burns at many different
speeds, and nothing seems to make a difference. At this point, it seems to me
that the problem is either with the kernel or cdrecord.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Try burning a cd with cdrecord 2.0-6, kernel 2.4.20-9, and a GCE-8520B cdrw
connected via USB 2.0.
Actual Results: The cd writer ruins the blank, freezes, and can't be used again
without cycling it's power and reloading the relevant kernel modules.
Expected Results: The cd should burn properly.
I suspect that this bug may be related to 81656, 88688, and 84160.
The 2.4.20-13 went out crooked in usb department, so skip it, please.
I hear some good news about 2.4.20-18, e.g. it "unhangs" an HP 8200e burner.
It is somewhat similar. Please try the -18 and let me know how it goes.
I upgraded to 2.4.10-18, and was able to burn successfully a CD with cdrecord
2.0-6. So it seems that, at least in my case, whatever had been wrong has been
corrected in the newer kernel.
