Hi Dave, and company, I have a question. Perhaps this is a known issue -- should I be looking in an archive somewhere? The crash command "mod -S" is messing up the address list. This is crash-4.0-7.6, running on ia64. Note how the value of module symbol xfs_ioerror_alert has changed after the mod -S. Is this a crash problem? Or my problem? (there are several ?'s in the mod -S output, including on the xfs module) crash> sym xfs_ioerror_alert a000000209955f80 (t) xfs_ioerror_alert crash> mod -S MODULE NAME SIZE OBJECT FILE a0000002093fc088 scsi_transport_spi 50672 /lib/modules/2.6.27.8-1-sgidev/ke rnel/drivers/scsi/scsi_transport_spi.ko mod: ioc4: last symbol is not _MODULE_END_ioc4?
