There are either conflicting patches or one of the patches for the gaming-sources kernel is broken/incomplete/incompatible. The result is "kernel BUG at ll_rw_blk.c:1041!" when trying to write to an UDF formatted CD. When only the packet patch is applied to a vanilla kernel, packet writing works fine on the same system (the packet patch is included in the gaming-sources kernels). The problem exists at least since gaming-sources-r2 and it's still not fixed in r5. http://warder.ath.cx:81/bugs/packet-err <- broken (gaming-sources-r5) http://warder.ath.cx:81/bugs/packet <- working (vanilla using the same .config) Reproducible: Always Steps to Reproduce: 1. emerge gaming-sources 2. make menuconfig (<M> Packet writing on CD/DVD media [Block devices]; <M> UDF file system support (read only) & [*] UDF write support (DANGEROUS) [File systems] 3. reboot in the new kernel and put CD-RW in the burner (modprobe pktcdvd; emerge udftools; pktsetup /dev/pktcdvd /dev/cdrom; cdrwtool -d /dev/cdrom -q; mount -t udf -o rw,noatime /mnt/cdrom; cp /etc/gentoo-release /mnt/cdrom; umount /mnt/cdrom) Actual Results: kernel crash -> http://warder.ath.cx:81/bugs/packet-err --------------------- elevator returned crap (-456204824) kernel BUG at ll_rw_blk.c:1041! invalid operand: 0000 .... --------------------- Expected Results: http://warder.ath.cx:81/bugs/packet
P.S. I think the packet patch comes from the ck ( http://members.optusnet.com.au/ckolivas/kernel/) patches which are applied to the gaming-sources as well. ck7 is available and bugfixes to ckvm, supermount and the elevator fixes are claimed which may solve the problem.
Created attachment 24136 [details] Updated gaming-sources ebuild Hi there, Would you mind trying this ebuild out and seeing whether this fixes your packet writing problem? This uses ck6 which should have an updated patch for packet-writing.
Well, that was a long time ago... I'm using 2.6 since test1 without packet writing problems. 2.4 is kinda obsolete (my opinion) and don't feel like wasting time on it :P If anyone else wishes to test it....
I see - thanks for keeping us informed. I've updated gaming-sources-2.4.20 with that ebuild if anyone still gets this, so I'm closing this as TEST-REQUEST.
