The following patch fixes the following problem (reported by Sergio):
| I'm having trouble with the GNU Mach of your tarball, it stalls with
| "panic: free_irq: bad irq number" just after the floppy disk
| detection. I've tried it on a P3 1000 Mhz laptop, on a AMD 700 Mhz
| tower and on qemu with the same result in all cases (no IRQ sharing
| problem).
since (also from Sergio):
| The problem seems to be a little bug (MAXIRQ value is 16, while
| reg_IRQ array range is 0-15) in eata_dma and eata_pio scsi drivers
| triggered by using gcc-4.0. Please try the attached patch, it works
| for me.
Here is the patch (once again from Sergio):
2005-10-29 Alfred M. Szmidt <[EMAIL PROTECTED]>
* linux/src/drivers/scsi/eata_pio.c (eata_pio_detect): Fix a
off-by-one error when probing.
* linux/src/drivers/scsi/eata_dma.c (eata_detect): Likewise.
* linux/dev/drivers/scsi/eata_dma.c (eata_detect): Likewise.
