Peter, Looking at these messages, and as you said earlier, the diag driver is getting loaded well after dasd_generic_probe tries to online the device. Interesting that I can't manually online the device after the diag driver finally gets loaded... Cheers...Pat

Apparently there are two problems: 1) mkinitrd does not include support for dasd_diag_mod - I'm assuming you specified the module using mkinitrd's --with= switch 2) a kernel bug prevents devices that failed to be activated during dasd module load to be activated later on Because of 1) and the fact that the --with switch adds modules too late in the initialization sequence, you seem to be running into 2). As a workaround, use the following method: mkinitrd initrd-<version> <version> --preload=dasd_mod --preload=dasd_diag_mod Regards, Peter -- Peter Oberparleiter Linux on System z Development IBM Deutschland Entwicklung GmbH ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
