Hi folks, after a long time, I tried to upgrade the kernel I use to boot some diskless PIII Katmai, C-PCI hosts (attached lspci -vv) with DEC ethernet chips.
I had trouble to use "IP auto configure" feature... It seems like it is skipped; even more, net/core/dev.c:net_dev_init() call by drivers/block/genhd.c:device_setup() is never called.
I remember that: 1) the IDE hd scan was done, with no devices found (it is diskless:-) 2) the net device driver was started, and it found 2 DEC chips
but a few lines later NFS root couldn't be mounted as no NFS server was set... anyway I had activated debug stuff in ipconfig.c and put a lot of printk/console_print in dev.c and none of them was displayed so I guess that code was never called actually.
then I added a bunch of printk/console_print in device_setup(), especially before blk_dev_init
------------------------------------------- #ifdef CONFIG_PARPORT parport_init(); #endif chr_dev_init(); console_print("before blk_dev_init()\n"); blk_dev_init(); sti(); #ifdef CONFIG_I2O i2o_init(); #endif #ifdef CONFIG_BLK_DEV_DAC960 DAC960_Initialize(); #endif #ifdef CONFIG_FC4_SOC /* This has to be done before scsi_dev_init */ soc_probe(); #endif #ifdef CONFIG_SCSI console_print("before scsi_dev_init()\n"); scsi_dev_init(); #endif #ifdef CONFIG_BLK_CPQ_DA cpqarray_init(); #endif #ifdef CONFIG_BLK_CPQ_CISS_DA cciss_init(); #endif #ifdef CONFIG_NET console_print("before net_dev_init()\n"); net_dev_init(); #endif ------------------------------------------------
(I used console_print as I was scared it could mess with irq by the sti() code...)
and all of a sudded it was all ok, I got all the printk/console_print...etc. I got NFS root mounting... everything OK!
hope it is useful to you.
ciao
