2.6.35 hangs on early boot in KVM
in [Kernel]

Prev: [ANNOUNCE] 2.6.33.7-rt29
Next: [PATCH 1/2 block#for-2.6.36] bio, fs: update RWA_MASK, READA and SWRITE to match the corresponding BIO_RW_* bits
From: Tvrtko Ursulin on 3 Aug 2010 05:30 I have basically built 2.6.35 with make oldconfig from a working 2.6.34. Latter works fine in kvm while 2.6.35 hangs very early. I see nothing after grub (have early printk and verbose bootup enabled), just a blinking VGA cursor and CPU at 100%. Config is attached. Any ideas what options I could toggle to debug this? I tried gzip instead of lzma but it isn't that. Thanks, Tvrtko Sophos Plc, The Pentagon, Abingdon Science Park, Abingdon, OX14 3YP, United Kingdom. Company Reg No 2096520. VAT Reg No GB 348 3873 20.

Just discovered I did not removed the quiet boot option, what I thought I have.. with that removed I see that it hangs just after "Booting the kernel." line.
