I also see this, and as no-one cared so far, I'm bumping Severity up. OS: SUSE Linux 9.3 Kernels tried (same results): SUSE's kernel-default-2.6.11.4-20a as well as a vanilla 2.6.11.9 hal-0.4.7-26 (SUSE) udev-053-15.2 (SUSE) hotplug-0.50-19 (SUSE) Relevant discussion around hwscan(d) took place on Linux-SCSI in November 2004, see <http://marc.theaimsgroup.com/?t=110048286400004&r=1&w=2> particularly <http://marc.theaimsgroup.com/?l=linux-scsi&m=110113027015843&w=2> - note thought that the assertion in the discussion 53C876 and higher fixed this is wrong, I can reproduce the problem on a 53C895 (as well as 53C860, 53C875, Matt Wilcox reproduced it on a 53C810A). hald attempts to read 4,096 bytes from the /sys/devices/pci0000:00/0000:00:0d.0/config file (which pertains to my SYM53C895 based Symbios SCSI adaptor) and gets 256 if run as root (64 if run as regular user). In these upper 128 bytes, some of the SYM53C8XX adaptors mirror their register block, and reading one of the registers causes the parity error, with major consequences such as GNOME hanging, CD-ROM disappearing from the bus, syslog excerpt below. Please make hald read only 128 (or perhaps 64 if sufficient) bytes from the /config file of SYM53C8XX devices. strace: 12750 12:12:48.546305 lstat64("/sys/devices/pci0000:00/0000:00:0d.0/config", {st_mode=S_IFREG|0644, st_size=256, ...}) = 0 12750 12:12:48.546377 stat64("/sys/devices/pci0000:00/0000:00:0d.0/config", {st_mode=S_IFREG|0644, st_size=256, ...}) = 0 12750 12:12:48.546449 open("/sys/devices/pci0000:00/0000:00:0d.0/config", O_RDONLY) = 12 12750 12:12:48.546497 read(12, "\0\20\f\0\27\0\0\2\1\0\0\1\20 \0\0\1\320\0\0\0\0\200\354"..., 4096) = 256 12750 12:12:48.553789 close(12) = 0 syslog: May 14 19:56:47 merlin kernel: sym0: SCSI parity error detected: SCR1=132 DBC=50000000 SBCL=0 May 14 19:57:18 merlin kernel: sym0:2:0: ABORT operation started.

David posted a patch against 0.4.7 to the hal list. The patch works for me. Find the patch at: http://lists.freedesktop.org/archives/hal/2005-May/002546.html Deep link: http://lists.freedesktop.org/archives/hal/attachments/20050516/b68022c6/hal-0.4.7-do-not-read-config-file.bin Fixed on hal-0_4-stable branch and part of hal 0.4.8 release. HEAD is not affected by this. Thanks. |
