I try to use packet-cd patch for writing cdrw as block
device
Now I install kernel 2.4.19-pre3-ac1 and latest packet patch
packet-2.4.19-pre2.patch.bz2
But I has same situation with 2.4.19-pre2-ac2
Packet drivers load successfully and pktsetup work OK (may
be). But when I try to do mount and got kernel oops
Decoded oops I insert bottom.
I ask about this trouble in packet-cd maillist but they said
to problem seems in udf module.
Can someone help me (Also in packet-cd maillist I read
messages about successful usage packet software in pure
kernel, not ac)?
There is decoded oops
ksymoops 2.4.1 on i686 2.4.19-pre3-ac1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.19-pre3-ac1/ (default)
-m /boot/System.map-2.4.19-pre3-ac1 (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
