2.5.48 and SCSI ?

Hello,

I have applied the patch sent today, but the kernel don't find my root (aic7xxx), what I got is:

Should I try without the patch?

Thank you very much,

Hello,

same result with vanilla with just this devfs patch:

802,804c802,804

<     struct timespec atime;
<     struct timespec mtime;
<     struct timespec ctime;

---

2512,2514c2512,2514

<     de->inode.atime = inode->i_atime;
<     de->inode.mtime = inode->i_mtime;
<     de->inode.ctime = inode->i_ctime;

---

2613,2615c2613,2618

<     inode->i_atime = de->inode.atime;
<     inode->i_mtime = de->inode.mtime;
<     inode->i_ctime = de->inode.ctime;

---

Isn't that the right fix for fs/devfs/base.c ?

Thank you very much,

Grégoire

I had the same problem with sym53c8xxx_2 when devfs was configured into the kernel (but not mounted). Then I made a kernel with devfs disabled and now this boots (and seems to work).

Hello,

well, I "need" devfs and it is mounted... I really don't want to create all the devices I use... At least now I know where does the prolem come from ;-)

Thank you very much,

Grégoire

Here's a patch you can try out, I already posted this to linux-scsi as a fix for /proc/scsi not showing up, I'll make sure James or someone pushes it to Linus' tree. I don't use devfs.

This is against linus bk but should apply fine against 2.5.48.
